language, is a powerful language offering many features–a wide variety of
datatypes, temporary objects, system and extended stored procedures,
scrollable cursors, conditional processing, transaction control, exception
and error handling, and much more. We’ll introduce those features later in
this chapter in the section “What is Transact-SQL?” Before getting to
Transact-SQL specifics, however, we’ll provide some background information
that will help you get a feel for the overall database environment in which
Transact-SQL operates. After we explain the basic differences between ANSI
SQL and Transact-SQL, we’ll jump back to more generalized topics. We’ll cover
the genesis of the relational database model and its impact on SQL programming
languages. We’ll talk a bit about normalizing data and introduce you to the
idea of row-processing and set-processing information technology. We’ll
spend a little time talking about the history of SQL Server in general.
Finally, we’ll introduce many of the features of the Transact-SQL programming
language itself.,SQL and the Introduction of Transact-SQLSQL, on which
Transact-SQL is based, started life in the mid-1970s as an IBM product called
SEQUEL. SEQUEL stood for Structured English Query Language. After a
permutation or two and some legal problems, IBM changed the name to
SQL–theStructured Query Language,. The language was designed to provide a
standard method for accessing data in a relational database. Ironically,
although IBM introduced SQL, Oracle was the first to bring a SQL-using product
to market.Today, many different relational database systems utilize SQL as
the primary means for accessing and manipulating data. When the American
National Standards Institute (ANSI) published a standard for the SQL language
in 1989, they set a universal standard to which database vendors could adhere.
Later, in 1992, ANSI released an update to the SQL standard, known as SQL-92.
The standards helped formalize many of the behaviors and syntax structures
of SQL. The ANSI standard covered lots of important details concerning the
querying and manipulation of data. The syntax was formalized for many
commands; some of these are SELECT, INSERT, UPDATE, DELETE, CREATE, and
DROP.Unfortunately, the standards didn’t address every facet of programming
for a relational database. To meet the needs of their own user communities,
database vendors began to extend the SQL language with capabilities that
enhanced the basic functionality of SQL. The Transact-SQL language was
introduced by Sybase to answer user requirements for programming extensions
to SQL–extensions enabling conditional processing, error handling, declared
variables, row processing, and numerous other functions. Even some of the
simplest operations, like creating an index or performing a conditional
operation, are extensions to the SQL language.Furthermore, many relational
database products had been on the market for some time before a standard of
any kind had been published. As a result, many developers began to implement
their own extensions to the SQL language. In most cases, these extensions
to SQL were incompatible from vendor to vendor. A program written in Oracle’s
dialect of SQL, for example, wouldn’t run properly under Sybase or DB2 and
vice versa unless it contained only the simplest ANSI-standard SQL
statements.,The Relational Database ModelThese days, relational database
management systems (RDBMSs) like SQL Server and Sybase are the primary engines
of information systems everywhere–particularly distributed client/server
computing systems. Though RDBMSs are now common enough to trip over, it wasn’t
always that way. Not too long ago, you would probably trip over hierarchical
database systems or network database systems or COBOL (heck,
thatstill,happens). Here’s a quick-and-dirty definition for arelational
database,: a system whose users view data as a collection of tables related
to one another through common data values.Perhaps you are interested in more
than a quick-and-dirty definition? Here goes. The whole basis for the
relational model follows this train of thought: data is stored intables which
are composed ofrows,andcolumns,. Tables of independent data can be linked,
orrelated to one another if all have columns of data that represent the same
data value, calledkeys,. This concept is so common as to seem trivial;
however, it was not so long ago that achieving and programming a system capable
of sustaining the relational model was considered a long shot with limited
usefulness.Relational data theory was first proposed by E. F. Codd in his
1970 paper to the ACM entitled “A Relational Model of Data for Large Shared
Data Banks.” Soon after, Codd clarified his position in the 1974 paper to
the Texas Conference on Computing Systems entitled “The Relational Approach
to Data Base Management: An Overview.” It was in this paper that Codd proposed
the now legendary 12 Principles of Relational Databases. If a vendor’s
database product didn’t meet Codd’s 12-item litmus test, then it was not a
member of the club. The good news is that rules do not apply to applications
development; rather, these rules determine whether the database engine itself
can be considered truly “relational.” Nowadays, most RDBMSs–including both
Microsoft and Sybase variants of SQL Server–pass the test.Codd’s Rules for
a Truly Relational Database SystemAre you curious about Codd’s 12 Principles
of Relational Databases? Don’t be ashamed that you don’t know them by heart;
few on the SQL Server’s development staff do, and no one on the marketing
staff does. However, the few folks whodo,know these principles by heart treat
them like religious doctrine and likely would be mortified by their
“lightweight” treatment here:,Information is represented logically in
tables.,Data must be logically accessible by table, primary key, and
column.,Null values must be uniformly treated as “missing information,” not
as empty strings, blanks, or zeros.,Metadata (data about the database) must
be stored in the database just as regular data is.,A single language must
be able to define data, views, integrity constraints, authorization,
transactions, and data manipulation.,Views must show the updates of their
base tables and vice versa.,A single operation must be able to retrieve,
insert, update, or delete data.,Batch and end user operations are logically
separate from physical storage and access methods.,Batch and end user
operations can change the database schema without having to re-create it or
applications built upon it.,Integrity constraints must be available and
stored in the metadata, not in an application program.,The data manipulation
language of the relational system should not care where or how the physical
data is distributed and should not require alteration if the physical data
is centralized or distributed.,Any row processing done in the system must
obey the same integrity rules and constraints that set-processing operations
do.,Transact-SQL and the SQL Server database management system accomplish
all of these functions.There is some debate about why relational database
systems won out over hierarchical and network database systems, but the
following reasons seem self-evident:,The relational high-level language
interface is much simpler to learn and more intuitive than with nonrelational
databases (you are, after all, reading thisbook as opposed to one on
Xbase).,Relational databases provide efficient and intuitive data structures
that easily accommodate ad hoc queries. From phone books to hotel registries,
relational databases (of a sort) are second nature to most people.,Relational
databases provide powerful integrity controls such as check constraints and
referential integrity–thus providing higher-quality data.,The RDBMS vendors
combined slick marketing and adept hardware positioning to gain a market and
mindshare advantage.,One of the key risks you face when developing relational
databases is their simplicity. They’re just soeasy,. It is no chore to slap
together a set of tables and columns for a database. Even assigning
relationships between tables is not a big deal. The whole process of database
creation can be accomplished so easily that many developers entirely skip
the distinct and separate process ofdatabase design,. There are literally
volumes of work written about proper relational database design, which is
beyond the scope of this text. But there are a few key concepts you must
understand fully if you’re going to leverage the power of relational databases
and, hence, Transact-SQL. Prominent among them are the concept of
normalization and the drastic difference in the set-processing behavior
preferred by SQL Server versus the row-processing behavior of popular rapid
application development (RAD) tools.NormalizationThere is an old urban
legend that claims the termnormalization,entered the database design lexicon
thanks to the late President Richard Nixon. It seems that the researchers
developing relational theory in the early 1970s were searching for a term
to describe the process of properly defining database tables and their
relationships to one another. Coincidentally, the news media were full of
stories about President Nixon “normalizing” the relationship between the
United States and the People’s Republic of China. Somewhere, over someone’s
head, a lightbulb went off and the term was introduced into the computer world.
Don’t bet any money on this story, but we have it on good authority from a
friend of a friend that this is true.So what is normalization used for?
Normalization is a design technique that enables database designers and
programmers to develop table structures that minimize programming problems.
As we discuss normalization, we’ll show you each set of problems that a
particular kind of normalization helps negate.The process of normalization
is characterized by levels of adherence callednormal form,. If a table design
conforms only to the lowest level of normalization, it is said to be inFirst
Normal Form which is abbreviated as 1NF. If a table design conforms to the
next higher level, it is inSecond Normal Form,(2NF), and so on. It is uncommon
and probably never necessary to take a table design beyondThird Normal
Form,(3NF). In fact, in some cases, it is actually advantageous in terms of
performance todenormalize,a table from a higher normal form back to a lower
normal form, like from 3NF to 2NF. It is also important to remember that
normalizing tables is not full database design; rather, it is an important
step in the analysis process. (The database design process is described
briefly inChapter 2, Database Analysis and Design,.)Assume that we are
keeping a database that contains information about all of our circus animals.
(What do you mean you don’t own any circus animals? Well, some of you have
kids, so that’s pretty close.)Unnormalized.The data, when completely
unnormalized, looks like this:Circus_Info Table, Unnormalized,1. animal_nbr
(the primary key),2. animal_name,3. tent_nbr,4. tent_name,5.
tent_location,6. trick_nbr1,7. trick_name1,8. trick_learned_at1,9.
trick_skill_level1,10. trick_nbr2...(and on through 16),11.
trick_name2...(and on through 16),12. trick_learned_at2...(and on through
16),13. trick_skill_level2...(and on through 16),In this example, the
animal_nbr column (in boldface) is our primary key, or the value that uniquely
identifies each row. This is anunnormalized,structure. But why go to the
trouble of normalizing it? Well, otherwise, there would be a number of logical
anomalies to deal with. In fact, there would be logic faults whenever you
attempted insert, delete, or update operations on this table. (Similar
problems are resolved each time you apply a higher level of normalization.)
The reason there are so many problems with this table design is that much
of the data is redundant and does not wholly depend on the key of the table
(animal_nbr). These are the main problems:Insert problemSuppose that a
chimpanzee has been acquired and has to be added to the table. It would be
impossible to add the new chimp without also adding a trick. Conversely, a
new trick couldn’t be added to the database without also assigning the trick
to a circus animal, which might not reflect the actual business rule.,Delete
problemWhat happens if a trick is deleted from the table? Unfortunately,
important data about a circus animal would also be deleted. The situation
also falters when an animal is deleted. This erases information about a trick
that may still be used by the circus.,Update problemUpdates in the
unnormalized table could cause actions on multiple records. Great care must
be taken to properly identify the appropriate record when making a
change.First Normal Form (1NF)To put this inFirst Normal Form,(1NF), we must
eliminate repeating groups. That means that any subgroups of data that appear
within the record should be split into separate tables. In this case, we have
at least two major repeating groups to split. Thus, our unnormalized structure
becomes two tables in 1NF:Circus_Animals Table in 1NF,1. animal_nbr (the
primary key),2. animal_name,3. tent_nbr,4. tent_name,5.
tent_location,Tricks Table in 1NF,1. animal_nbr (the concatenated key),2.
trick_nbr (the concatenated key),3. trick_name,4. trick_learned_at,5.
trick_skill_levelNow that our tables are in 1NF, we have the obvious advantage
of reduced space consumption. Plus, an animal that only knows a few tricks
doesn’t use up the space allotted for 16 tricks in the unnormalized table.
On the flip side, the animal can also know more than 16 tricks. Also note
that in the Tricks table, the key had to be expanded to include both animal_nbr
and trick_nbr. Concatenated keys are often the byproduct of the normalization
process.Second Normal Form (2NF)Let’s take our 1NF circus tables toSecond
Normal Form,(2NF) by eliminating partial dependencies. Say what? Apartial
dependency,is a fancy word for data that doesn’t depend on the primary key
of the table to uniquely identify it. For example, the trick name appears
in every animal record, but the trick_nbr should be sufficient since we’ve
already got the name in the Tricks table.So this 1NF table:Tricks Table,1.
animal_nbr,2. trick_nbr,3. trick_name,4. trick_learned_at,5.
trick_skill_level,becomes these 2NF tables:Tricks Table,1. trick_nbr,2.
trick_nam,Animal_Tricks Table,1. animal_nbr,2. trick_nbr,3.
trick_learned_at,4. trick_skill_levelAnimal Table in 2NF,1. animal_nbr,2.
animal_name,3. tent_nbr,4. tent_name,5. tent_locationUnfortunately 2NF,
like 1NF, has its own logical faults when attempting data manipulation:Insert
problemAssume that we want to create a new record to represent a tiger assigned
to the “Big Cats” tent. It’s impossible to create an additional tiger record
for the Animal table without first creating a new tent. This is due to the
fact the tent_nbr column has a transitive dependency to the animal_nbr column,
which more uniquely identifies its information than does the tent_nbr
column.,Delete problemDeleting a particular animal might result in the loss
of an entire tent, even though you still want to retain information about
that tent. For example, deleting the sole ostrich in the circus completely
removes all traces of the “Big Birds” tent, since you only have one of these
large birds.,Update problemTent information is redundant in the Animal table,
so any change to tent information require a search of the entire table to
locate the records needing alteration. Plus, the number of the records
requiring the update may vary over time.An additional step of normalization
is needed to eliminate these logic faults. This added step converts a 2NF
table into a 3NF table.Third Normal Form (3NF)To take this motley crew of
tables toThird Normal Form,(3NF), we must now take 2NF tables and eliminate
all transitive (i.e., hidden) dependencies. In other words, every column that
isn’t a part of the key must depend on the key for its informational value.
Non-key columns should have no informational value if they are separated from
the key of a 3NF table. Remember that the term “eliminate” doesn’t mean
“delete.” Instead, it means to split into separate tables.Our tables in 3NF
would now look like this:Tricks Table (unchanged, it was already 3NF!),1.
trick_nbr,2. trick_name,Animal_Tricks Table (unchanged, it was already
3NF!),1. animal_nbr,2. trick_nbr,3. trick_learned_at,4.
trick_skill_levelThe Animal table becomes two new 3NF tables:Animal_Lodging
Table in 3NF,1. animal_nbr,2. animal_name,3. tent_nbr,Tents Table in 3NF,1.
tent_nbr,2. tent_name,3. tent_location2NF and 3NF are all about the
relationship between non-key and key fields. A 3NF table should provide a
single-value fact about the key and should use the whole key (if
concatenated), and nothing but the key, to derive its uniqueness.By the time
you get to 2NF, the columns all depend on the primary key for their identity.
However, the columns may have such a distinction from other columns in the
table that they should be split out into a separate table. In the
Animal_Lodging table, the tent_nbr still appears as a non-key column in the
table, even though it is the primary key of the Tents table. Thus, tent_nbr
is a foreign key within the animal_Lodging table. Using tent_nbr as a foreign
key, we are able to join the data together from the two separate tables to
form a single data set.Remember, normalizing data means eliminating redundant
information from a table and organizing the data so that future changes to
the table are easier. A table is in First Normal Form (1NF) when each field
contains the smallest meaningful data and the table contains no repeating
fields. Second Normal Form (2NF) refers only to tables with a multiple-field
primary key. Each non-key field should relate to all of the fields making
up the primary key. Third Normal Form (3NF) refers only to tables with a
single-key field and requires that each non-key field be a direct description
of the primary key field.NOTE:The steps described here are merely guidelines
that help you design a set of stable table structures.Beyond 3NF?There are
additional steps in normalization used to solve other specific logic faults
in table design; however, they are seldom practical in the use of nonacademic
applications. Read on for a quick glimpse of normal forms beyond
3NF:Boyce-Codd Normal Form (BCNF),Ensures that absolutely no hidden
dependencies exist by splitting off tables if determinatecolumns exist in
a 3NF table. A determinate is a column on which some other column is fully
functionally dependent. This would be akin to splitting the store_dept table
into two tables: one called store_dept, which contains only store_nbr and
dept_id, and the other called dept_name, which contains only dept_id and
dept_name.Fourth Normal Form (4NF),Compensates for multivalued dependencies
in a three-column table (of A, B, and C), where columns A and B have a
well-defined relationship, columns A and C have a well-defined relationship,
but columns B and C are completely independent.Fifth Normal Form (5NF),Almost
a purely academic exercise, SNF reduces offset joins and projection
dependencies that cause spurious results, hence called Join-Projection
Normal Form.Domain-Key Normal Form (DK/NF),Introduced by Donald Fagin back
in 1981, it solves most insertion and deletion logic faults and provides
generic definitions of deriving normal forms. However, no methodology or
standardized algorithm exists for deriving DK/NF.DenormalizationYou’ve just
read all about how and why to normalize tables. Designing table structures
to 3NF reduces data redundancy and provides clean, logical table structures.
But now we’re going to tell you all the reasons todenormalize,tables. Odd
as this might sound, denormalization is not diametrically opposed to
normalization (although some purists might testify otherwise).The main
benefit of denormalization is improved performance, although simplified data
retrieval and manipulation are sometimes lesser benefits. Both of these
benefits are rendered through the reduction in the number of joins needed
for the proper functionality of your application.Joins,(described inChapter
3, SQL Primer,) merge the data of two related tables into a single result
set, presenting a denormalized view of the data. Joins, however, are rather
time consuming and utilize a lot of CPU cycles. So, to reduce the expense
of joins, many developers preempt what would otherwise be a very common join
with a denormalized table. The table is now exposed to the vulnerabilities
inherent in its lower normal form, but considerable time is saved because
the application no longer has to join multiple tables together in a temporary
workspace. Denormalization can also save processing time that might have been
spent on the creation of summary reports.The first thing you need to remember
about denormalization is that you must thoroughly understand the needs and
behavior of the data. There are some other tips to keep in mind when
considering denormalizing tables:,Denormalization means that more storage
space will be needed for the redundant data.,Redundant data usually speeds
up queries but can slow down updates since multiple instances of the data
item must be altered.,Denormalized tables can introduce logic faults that
must be compensated for in the application code.,Maintaining integrity can
be more difficult with redundant data.,Denormalization yields the best
improvements on tables that are frequently queried, such as validation tables
or reporting tables. Tables in which records are frequently inserted,
updated, and deleted are less viable candidates for
denormalization.,Denormalization is generally regarded as a tuning method
of last resort by the purists. On the other hand, many database administrators
feel that it is perfectly natural to denormalize a frequently-used eight-way
join to create a simpler three-way join, for example. Denormalization is
usually accomplished by adding columns and foreign keys from other tables
into the denormalized table or by adding aggregate columns to the denormalized
table. If every query issued against a given table commonly has to join to
columns from one or more other tables, you’re looking at a candidate for
denormalization.,Row Processing Versus Set ProcessingOne of the first things
an experienced third-generation language (3GL) programmer must do when
learning Transact-SQL (or any SQL variant, for that matter) is toss all her
programming techniques and tricks out the window. Yes, you must unlearn much
of what made you a star 3GL programmer to become a star database programmer.
Procedural 3GLs, like FORTRAN, COBOL, or BASIC, perform their data operations
in a manner that is quite contrary to effective Transact-SQL programming.
That is because the basis of 3GL data manipulation requires the programmer
to actually tell the program exactly how to treat the data, one record at
a time. Since the 3GL program cycles down through a list of records, performing
its logic on one record after the other, this style of programming is
frequently calledrow-processing,ordeclarative programming,. Using this
style of programming in Transact-SQL programs does to SQL Server what a parade
does to traffic–slows things down.On the other side of the equation, programs
written for SQL-based RDBMSs prefer to operate in logicalsets,of data. Unlike
the row-processing style, you tell SQL Server onlywhat,you want for the data,
nothow,each individual piece of data should be handled. Sometimes you will
seeset processing,referred to asprocedural processing since you code only
what you want, as in “Give me all employees in the southern region who earn
more than $70,000 per year.”To use an analogy, assume that you want to buy
a long list of automobile parts for the 1970 Oldsmobile 442 convertible you’re
restoring (well, that’s the car I’d want to restore). You go to the first
parts store on your list. There you have to pull out a shopping cart and wheel
it up and down every single aisle searching for the parts you want.
Furthermore, when you find a part you need, you have to take it out of the
shipping crate and, later, you have to barscan it and bag it yourself. That
is what row processing is like. To compare set processing in the analogy,
you take the same list to another store, where you hand it to a clerk at a
receiving window. The clerk disappears behind the window, presumably to fetch
your parts. Why’s it taking so long? Is he having a talk at the water cooler
or getting your parts? You really can’t tell, because you can’t see past the
partition, but soon enough he returns with all your parts, packaged up and
ready to go. It seems that the clerk has been gone a long time. But, in reality,
the clerk got your list ready much faster than you would have at the first
store, because he was able to skip all the aisles that didn’t have the parts
you wanted. It’s very similar with set processing.,The History of SQL
ServerSQL Server, like many things related to SQL, is a story of diversity.
At one time, both Sybase and Microsoft had virtually the same product. Today,
the two products are growing increasingly divergent. In fact, Sybase now calls
their implementation of the product Sybase Adaptive Server Enterprise. For
purposes of simplicity, in this book we refer to both Microsoft and Sybase
implementations as SQL Server.Today, major differences in the two
implementations are largely a result of their most popular operating system
and hardware platforms. Sybase Adaptive Server Enterprise is deployable on
many operating systems, including Windows NT and stalwart Unix platforms.
Adaptive Server has many features that leverage Very Large Database (VLDB)
and multithreading capabilities. Sybase carries the Transact-SQL language
uniformly throughout their product line. So, you’re just as likely to see
Transact-SQL programs on the powerful and mobile Sybase SQL Adaptive Server
Anywhere (formerly known as SQL Anywhere) running on Windows 95 and Windows
98 computers. Going to the high end of the spectrum for online analytical
processing (OLAP) and data warehouses, Sybase Adaptive Server IQ utilizes
Transact-SQL for programmatic needs and, in fact, utilizes the same parser
as Sybase Adaptive Server. Conversely, Microsoft has focused on ease of use
and administration, as well as tightly integrating the product with other
no-cost features like replication and alert forwarding. In any event, all
of these database platforms provide their respective user groups with
efficient and effective database management tools.Today, there’s a good deal
of discussion about encapsulating Java as the primary SQL programming
extension for not only Sybase and Microsoft but also for competitors like
Oracle. Even with this alternative looming in the distance, Transact-SQL will
enjoy many years of active support and augmentation by the vendors. Even if
you know or are learning Java, you’ll still have to know Transact-SQL to excel
on either Sybase or Microsoft database platforms. Heck, the
backward-compatibility issues alone are enough to ensure that Transact-SQL
will have many, many more years of coding ahead.But that’s the present and
future. Maybe you want to know about how things got to be the way they are?
By reading this section, you are actually making an admission that many
programmers and analysts are loath to: history is interesting or perhaps
evenenjoyable,.This is not actually a sign of weakness as some might attest.
With tongue planted firmly in cheek, please read on. Table 1-1 shows the
evolution of both Microsoft and Sybase’s versions of SQL ServerTable 1-1:The
Evolution of SQL ServerTime,Event1987,Microsoft and Sybase announce a
technology and marketing partnership. Microsoft gets exclusive rights to
market Sybase’s DataServer product on OS/2 and all Microsoft-developed
operating systems. Sybase gets royalties and added credibility in the Unix
and VMS markets. Sybase ships its first commercial DBMS product, called
DataServer, for Sun workstations running Unix.1988,Microsoft and Ashton-Tate
announce a marketing partnership. Microsoft can’t put a dent in dBase’s
tremendous market presence. Ashton-Tate wants access to Sybase’s powerful
multiuser database management technology, which ships this year. Microsoft
forms a three-way alliance.1989,Ashton-Tate/Microsoft SQL Server Version 1.0
ships.1990,Ashton-Tate dBase IV was floundering. Microsoft wanted to beef
up its offerings for the new OS/2 LAN Manager product. Microsoft and
Ashton-Tate quit the partnership. "Microsoft SQL Server" Version
1.1 ships by summer with support for Windows 3.0.1991,A proliferation of
Windows 3.0 front-end tools spurs the growth of Microsoft SQL Server. Later
that year Microsoft and Sybase amend their contract to allow Microsoft to
make actual bug fixes–all under Sybase supervision. IBM and Microsoft call
off their OS/2 partnership with Microsoft to focus on Windows. Sybase
surpasses $100 million in revenue and goes public on NASDAQ.1992,Microsoft
and Sybase SQL Server 4.2 ships. Microsoft diverts its attention away from
OS/2 and into Windows NT. Microsoft SQL Server for Windows NT later ships
its beta release while Sybase ships its much-vaunted System 10.1993,Microsoft
Windows NT 3.1 ships, closely followed by Microsoft SQL Server. By 1994,
Sybase SQL Server System 10 and Microsoft SQL Server were competing
unabashedly as the two formally ended their partnership.1995,Microsoft SQL
Server 6.0, a very significant release, ships in June. Sybase ships the highly
lauded, technically potent Sybase SQL Server 11. Sybase and PowerSoft merge
to form the seventh largest independent software house.1996,Microsoft SQL
Server 6.5 goes into production. Sybase Adaptive Server Enterprise 11.5
production ships.1997,Microsoft SQL Server 7.0 beta ships. Sybase ships the
production version of Adaptive Server Enterprise 11.5.1998,Sybase Adaptive
Server Anywhere 6.0 ships in the summer, while the Adaptive Server Enterprise
11.9.2 production release goes out the door in September. Microsoft SQL Server
7.0 ships release to manufacturing copy late in the year.,What Is
Transact-SQL?The name Transact-SQL isn’t exactly self-explanatory, but it
does imply the idea of “transactional” extensions to the SQL database
programming language. Transact-SQL isn’t a standalone product. You can’t use
it to write applications in the same way you could with C++ or Java. Instead,
Transact-SQL is the main enabler of programmatic functionality within the
relational databases provided by Microsoft and Sybase. Transact-SQL is very
closely integrated with SQL while adding programming capabilities not already
standardized within the SQL database programming language. At the same time
Transact-SQL extends SQL, it also integrates seamlessly with it.In the
following sections, we’ll show you some of the capabilities of Transact-SQL,
along with some rudimentary examples. Don’t worry if the examples don’t
immediately make sense to you. After a little study, you’ll see that these
are relatively simple sets of code.Here’s an example of a stored procedure
in which Transact-SQL statements and SQL statements are combined to provide
useful functionality. The following little program allows you to selectively
delete old information from the sales table of the pubs database (we’ll
explain this database inChapter 2) based ontheorder_id. The business rule
being applied here is “Don’t allow a delete from the sales table unless the
data is more than two years old.” Sounds like a simple proposition, doesn’t
it? But it’s not all that simple. Implementing a sensible business rule like
that in a Microsoft or Sybase database requires the combination of both SQL
and Transact-SQL statements:-==-,Our simple task was to allow a user to purge
records more than two years old from the sales table based on the ord_id stored
in the table. To accomplish this task, we had to utilize the Transact-SQL
components of an IF . . . ELSE construct, variables, the DATEDIFF and GETDATE
functions, and finally a RAISERROR statement for error handling. To finish
things off, we added a bit of commentary (as all good programmers should)
using Transact-SQL extensions to explain what the heck we’re doing. At the
same time, we had to combine those commands with a basic SQL DELETE statement.
This synergy of SQL and Transact-SQL enables you to implement powerful
applications and information systems.Programming ConceptsWhen you write a
program in a third-generation language (3GL) and even most other
fourth-generation languages (4GLs), you’re looking at a whole other animal.
While programs in third-generation and fourth-generation languages can be
entirely self-contained, Transact-SQL programs in a sense are merely
extensions of the database environment.To explain more fully, programming
in Transact-SQL is a blend of several distinct, yet integrated, components.
Let’s say that you’re about to begin developing a new application. You’ll
probably start out with a period of design and analysis in which you’ll map
out what the database will (probably) look like. You’ll build your development
database using declarative SQL statements or perhaps a visual data- modeling
tool. You might later implement a set of complex business rules on your
database tables through triggers coded in Transact-SQL. From there, you might
create reports and business processing modules that support the user
interface through stored procedures coded in Transact-SQL.Meanwhile, another
group of programmers may have begun building the graphic user interface via
a client/server or web application development tool. They might utilize a
technology that connects their Java-based application to your database
backend. When the frontend graphical user interface performs certain
transactions, they may actually call the stored procedures you’ve coded and
stored on the server, or their application may initiate transactions that
fire triggers on some of the database tables.This hodgepodge of technologies
and programming environments may seem daunting at first. For some developers
who have grown up in the structured world of third-generation languages like
FORTRAN or COBOL, the comfortable and proven methodologies are no longer 100%
effective. At the other end of the spectrum, novice developers may drift about
without any structure, cranking out report after report and screen after
screen without giving a second thought to documentation, maintainability,
or code reusability. The truth is that no matter what background you come
from, you must adjust to the different types and techniques of coding you’ll
face when developing a new application. For what this blend of technologies
introduces in terms of challenge, it adds even more in terms of flexibility
and power.The kernel features of Transact-SQL are described in the following
sections.A Wide Variety of Datatypes for Variables and ConstantsTransact-SQL
lets you declare and then utilize local variables and constants within a
Transact-SQL object. These variables and constants must be of a datatype known
to the database, like VARCHAR or INT. Special-purpose datatypes exist within
Transact-SQL to provide a special functionality. For example, the IDENTITY
datatype is used to store an automatically increasing numeric counter within
the column of a given table. TIMESTAMP is another special-purpose
Transact-SQL datatype that is used to stamp each record of a given table with
a unique marker.Additionally, you can construct your own special-purpose
user-defined datatypes on top of an existing system datatype. These
user-defined datatypes enable you to constrain the use of, or data stored
within, a variable or constant of your special datatype.Present in Sybase
Adaptive Server and new to Microsoft SQL Server Version 7.0 are several new
Unicode datatypes, including NCHAR, NVARCHAR, and NTEXT. These new datatypes
allow data storage that is independent of the local language character set.
Other new datatypes found in Microsoft SQL Server 7.0 include the
UNIQUEIDENTIFIER, which uniquely distinguishes each row in a table even
across multiple servers, and the CURSOR datatype, which facilitates the use
of cursors within a Transact-SQL program.Programmer-Defined Temporary
ObjectsTransact-SQL provides several useful temporary objects that endure
only as long as the current session. These temporary objects include tables
and stored procedures. The objects are stored in the tempdb database and can
be used for short-term applications that need exist only while a user is
connected or a system operation is executing. Temporary tables can have all
the trimmings of their more permanent counterparts, including indexes,
constraints, and triggers. Temporary tables are very useful as a sort of
“holding tank” where data can be massaged and manipulated into a more useful
format. In some cases, temporary tables are used to simulate the functionality
of an array found in a third-generation language.Here’s an example of the
definition of a temporary table that also populates the temporary table with
data:-==-,Using the speedy SELECT . . . INTO syntax enables you to quickly
create and populate a temporary (or permanent) table with data. There are
good and bad times to use the SELECT . . . INTO statement. Temporary tables
are designated by a single pound sign (#) as a prefix. They are usable only
by the user or process that created them. Global temporary tables are
designated by double pound signs (##). Global temporary tables are available
to all users or processes as long as the creating user or process remains
connected to the database server.Specialized Functions and Global
VariablesUnlike local variables, which are declared by the programmer in the
body of a Transact-SQL program, global variables and functions are provided
by Microsoft and Sybase to augment your programming toolset. Global variables
enable you to immediately retrieve a particular piece of system information.
For example, the global variable @@connections allows you to see how many
connections have been attempted since the last time the server was started.
The global variable @@error shows the last error number generated within the
current user’s session (or a 0 if the last command was successful).Functions,
on the other hand, allow you shortcuts to manipulate and manage data. There
are a large number of functions to choose from, but they fall into these basic
categories:Aggregate functionsAggregate functions compute a single value
result, such as the sum or average value of a given column in a
table.Conversion functionsThere are a few versatile functions within
Transact-SQL that allow you to convert data from one datatype to another or
to reformat data.Date functionsDate functions manipulate DATETIME and
SMALLDATETIME values.Mathematical functionsThese functions provide
statistical, trigonometric, logarithmic, and exponential capabilities when
manipulating numbers.String functionsA number of string functions allow you
to analyze and modify CHAR, VARCHAR, and, in some cases, TEXT columns and
variables.System (niladic) functionsSystem functions allow you to retrieve
information from system tables and parameters. In this usage, they are
somewhat like global variables. Some system functions also provide a way to
perform logical comparison of data.Text and image functionsManipulation of
TEXT and IMAGE data differs from other types, because they have several usage
restrictions. Transact-SQL provides several specialized functions to support
the use and manipulation of these datatypes.System and Extended Stored
ProceduresIn addition to the wide variety of system functions and global
variables, Microsoft and Sybase supply system stored procedures and extended
stored procedures, which provide ready-made programs and/or powerful
extensions to Transact-SQL. Here are some examples of system and extended
stored procedures:sp_adduserA system stored procedure that allows you to add
a new user to a database,sp_helpA system stored procedure that shows detailed
information about a wide variety of database objects,sp_lockA system stored
procedure that details the locking by user and system processes within the
database server,sp_whoA system stored procedure that shows what user and
system processes are active within the database server,xp_cmdshellAn
extended stored procedure that allows you to execute any operating-system
command-line executableYou might, for example, use the xp_cmdshellextended
stored procedure to ensure that a necessary file exists before performing
a data load operation.Control-of-Flow OperationsTransact-SQL provides
procedural extensions to SQL that provide several different control-of-flow
structures:,Conditional processing with IF . . . ELSE,Iterative processing
with WHILE,Branching control with GOTO,Delay control with
WAITFOR,Conditional processing with the IF . . . ELSE construct allows your
Transact-SQL program to make choices. You can nest your IF . . . ELSE
conditionals as deep as you’d like. The IF . . . ELSE construct requires the
use of a BEGIN . . . END block if more than one SQL or Transact-SQL command
is dependent upon the condition. The result of this coding constraint is a
structured, block orientation. Here’s an example of an IF . . . ELSE
statement:-==-,The Transact-SQL WHILE extension provides iterative controls
that allow a single block of Transact-SQL code to be repeated. You can even
nest loops within other loops. In the simple example that follows, an output
line is constructed and printed 12 times, once for each month. This example
shows what a WHILE loop looks like:-==-,You have some other useful
control-of-flow statements in the GOTO command and the WAITFOR command. GOTO
transfers control from one executable statement to another labeled section
in the current Transact-SQL program. The WAITFOR command provides
Transact-SQL programs with delay controls. Here’s a Transact-SQL program that
illustrates both commands:-==-,Row-Based Operations Using CursorsAs we
discussed earlier, one of the most potent features of relational database
management systems is their ability to process data in sets of records rather
than on a row-by-row basis. Set-based processing is very fast, but it is
limiting in that you cannot selectively modify a single record within a given
result set. Transact-SQL has extended this set-based functionality to
row-based operations usingcursors,.Cursors allow you a high degree of control
over the manipulation of data within your database. In a sense, a cursor is
a SELECT statement that steps through its result set one record at a time.
To properly use a cursor, you must declare, open, fetch from, and close a
cursor. In many cases, you also should deallocate the cursor. Interestingly,
you can use a cursor to scroll forward or backward through a result set. You
also can set a cursor to step through a table one record at a time or to skip
along several records per step.The following example shows you all the steps
needed to properly utilize a cursor:-==-,Error HandlingTransact-SQL allows
you to detect the occurrence of errors in the course of executing a program.
Errors in Transact-SQL fall into three categories: informational, warning,
and fatal.,Informational errors output a message but do not cause the program
to abort.,Warning messages output an error message and abort the currently
executing SQL or Transact-SQL statement but do not abort the entire program
or Transact-SQL batch.,Fatal errors are baaaad. They send an error message
and a notification to the operating system error log. Furthermore, fatal
errors terminate the Transact-SQL program where the error
occurred.,Transact-SQL uses a linear code model for error handling. So, if
you don’t check for a particular level or type of error, Transact-SQL will
not provide any special response to it. For that reason, it is very important
for you to properly check and evaluate error conditions throughout the
execution of your Transact-SQL programs.The following Transact-SQL block
checks to see if certain data exists within the database. If the data doesn’t
exist, then an ad hoc error message is raised:-==-,Both Microsoft and Sybase
also provide you with the ability to add your own user-defined error messages
into the system error message table, sysmessages. This capability allows you
to define a set of error messages specifically for your application and embed
them in the database, rather than solely within the Transact-SQL program
logic.Transact-SQL Objects and Transaction ControlOne of the key features
of Microsoft SQL Server and Sybase Adaptive Server is the ability to store
Transact-SQL objects (triggers, views, and stored procedures) within the
database itself. These blocks of Transact-SQL code can then be invoked by
any user or system session that has adequate privileges to perform the task.
In fact, both Sybase and Microsoft support the use of remote procedure calls
(RPCs), allowing a single local server to invoke a stored procedure on a remote
server. Through Transact-SQL objects, the database becomes a repository for
both application code and data. Transact-SQL objects are stored in their own
memory area, the procedure cache, within the database’s memory space.At a
more elemental level, transactions can be closely controlled and monitored
in a Transact-SQL program using the global variables @@transtate and
@@trancount. Atransaction,is a SQL or Transact-SQL statement that produces
a measurable unit of work by retrieving, inserting, deleting, or modifying
data. You can allow Transact-SQL to use implicit transactions, or you can
explicitly define a transaction using the BEGIN TRAN, COMMIT TRAN, and
ROLLBACK TRAN statements. By properly gauging and constructing your
transactions, you can greatly reduce or even eliminate the possibility of
blocks in an application supporting multiple concurrent connections.Tracing
and DebuggingA wide variety of tracing and debugging features are supplied
by Transact-SQL using the DBCC and SET commands. In addition to providing
tracing and debugging capabilities, these commands allow you to control
server behavior, monitor performance, and alter the session environment and
behavior.The DBCC command offers functions that fall into several general
categories:Database consistency checksCommands like DBCC NEWALLOC and DBCC
UPDATEUSAGE check a given database for inconsistencies in the data and, in
some cases, take remedial action.,Database and server configurationIn dire
straits, you can use DBCC command to drop or shrink
databases.,DebuggingCommon debugging applications for the DBCC command
include controlling tracing functions and examining the input and output
buffer of various system and user sessions on the database
server.,Performance tuning and monitoringA wide variety of DBCC commands
allow you to monitor the behavior and performance of the server. Other
commands enable you to pin tables into memory, rebuild indexes, reestablish
fillfactors, or display the selectivity and value of a given
index.Conversely, the SET command enables you to mandate specific behaviors
for a given session or user connection. You can use the SET command to enable
or disable certain ANSI standards, determine deadlock resolution preference,
and perform a wide range of other functionalities.Special Aggregate
OperatorsTransact-SQL, under Microsoft SQL Server, has grown to support new
aggregate operators, such as ROLLUP and CUBE, that are specifically optimized
for very large databases, such as those found in data marts and data
warehouses.CUBE and ROLLUP are optional operators of the GROUP BY clause of
a SELECT statement. A SELECT query using GROUP BY WITH CUBE returns all rows
that it would return without the CUBE switch. In addition, it produces summary
rows for every possible combination of GROUP BY keys. A query using WITH ROLLUP
returns just a subset of the rows produced by WITH CUBE. ROLLUP is useful
in computing running sums and running averages. Unlike CUBE, which computes
aggregates for any possible combination of keys of GROUP BY, ROLLUP is
sensitive to the order of items in the GROUP BY.Here’s an example of a SELECT
statement and result set with a SUM aggregation and a simple GROUP BY
clause:-==-,type     pub_id Sum———— —— ———–business 0736business

operator, we get this:SELECT type, pub_id, SUM(ytd_sales)FROM titlesGROUP

of NULL per pub_id and a grand total of all titles sold:type    pub_id Sum————

Comes with a CD-ROM containing extensive examples.,If you're a salesman and
you want to survive in the used auto parts industry, the first thing you'll
want to focus on is building customer accounts. I hate to be the one to tell
you this but your paycheck will not rely on walk-in customers alone. In order
to survive in the economy you find yourself in today, you'll need to have
many different types of customer accounts, and you'll need to take care of
each one like it was your last. Customer accounts are your bread and butter
and the walk-in customers are just gravy. You need to make sure you look at
it this way or you'll find out pretty quick that a gravy diet simply doesn't
have any filling.If you're wondering what type of customer accounts I might
be speaking about, here are a few that might get you started:" Body Shops,"
Auto Repair Shops," Machine Shops," Brake Shops," Muffler Shops," Service
Centers," New Auto Parts Stores," Dealerships," Warranty Companies,"
Insurance Companies," Other RecyclersThe used auto parts industry spans to
almost every type of company you can think of and to be honest, each one of
these companies will buy from you, every single day. Will they just
mysteriously ring your private line and start doing business with you? NO!
You have to go out and do some work to get these places to call you, and call
you on a consistent basis. Do you want to know just how this is done? If so,
keep on reading this article because I have a plan that has never failed me
in the 30 years I've been in the auto recycling industry.The first thing you
don't want to do is start calling different companies, I'll write an article
on that one later. For now, you'll need to focus on what I call the 'Warm
Market.' That's right; the warm market consists of companies that have already
done business with your company. These are companies that have already spent
money with the business you're working for, therefore they're the easiest
companies to capture and persuade to purchase used auto parts. There isn't
much persuading since they've done it in the past, so it makes it that much
easier for you to get them to ring your phone.The way you find your warm market
is in your companies customer file. Most companies nowadays have everything
on computer and this makes it very simple. Now, if you're new and your company
is really on their toes, they probably have salesman servicing customer
accounts on a daily basis. You want to know something? 90% of the used auto
parts recyclers aren't on their toes and after reading this you'll know what
I'm talking about. If you don't know how to do this next step, you might want
to have someone in the office do it for you. You want to build a report on
your existing customer accounts. You'll want to find your warm market by zip
code. Start with the closest to you and work your way out. The report will
need to have these fields; business name, address, phone number, contact,
last date of purchase, over all purchases for the last 12 months, and date
or last purchase.OK, this is what separates the hungry sales people from the
slackers. You will take this report and sort it working from the last date
of purchase. You want to deal with accounts that haven't bought from you in
the last 6 months. When you have all this information in front of you, pick
20 shops and separate them. This will now be known as your 'Book-of-Business.'
For the next 30 days you are going to contact every single one of these shops
and begin by introducing yourself and letting them know where you are from.
Do not try and sell anything unless 'they' want to purchase something. The
initial calls are only to get to know them, and for them to get to know
you.Remember, 30 days. Starting at the top of your list you will call each
shop until you're done, then start over. After the first call, phone them
to ask how they are doing, do they need anything today, would they like more
information, do they have any information about their business you could share
with your other customers (this is good). Just keep the conversation going
and make sure they have your direct line or a way to get a hold of you
specifically. This is how you begin to build customer accounts in the used
auto parts industry. Once you've gone through your list and you have begun
to make sales you'll find some shops aren't buying, (don't worry) replace
them with new leads from your main report and start the process over with
the newly added accounts. Now, go out and build some customer
accounts.,,There's a question a lot of people are asking themselves. Where
can if research or buy a new car? Well it looks like you've taken the first
step into finding where to research or buy your new car - you're reading this.
Modern life has taking car buying to a new level.Online!,There are mane web
sites that do the job for you. Many of them just require for you to type in
you name and email and they'll send you a quote for your new car in a matter
of minutes! The thing is that most people I've talked to often tell me that
when they are researching for a new car they are looking for information on
auto loans.That's the hard part! But not because it's difficult to find a
good car loan. As a matter of fact, its quite the opposite. There a countless
of online car loans, the thing is to find the right one for you. Many web
pages offer car loans with high auto loan rates or have difficult requirements
for you to apply for them.Private Auto LoansAnother thing that many web site
lack to mention is the existence of private auto loans. I myself had a hard
time researching for buying my new car because I had bad credit, had no idea
where to look for information on loans, and I needed a car ASAP.Private
automobile loans exist for those that, or have no credit score or, like me,
have a bad credit score. The general requirements for those car loans is just
your credit history, what car you want to buy, and bank statements for the
last three months. Or at least that's what they asked me for. You should look
into these kind of loans, they are pretty useful if you know how to handle
them. I hope you know have a better idea to the answer for, "Where can I
research or buy a new car?",,Where To Get Cheap Auto Parts Car Acce
