turn the row when col1 is equal to zero).

not evaluate to TRUE—meaning that col1
is not 0—does the second WHEN clause
check whether the expression 10/col1 > 2
evaluates to TRUE. If it does, the CASE
expression returns the string ‘yes.’ In
all other cases, the CASE expression re-
turns the string ‘no.’ The predicate in the
WHERE clause returns TRUE only when
the result of the CASE expression is equal
to the string ‘yes.’ This means that there
will never be an attempt here to divide by
zero.

This workaround turned out to be quite
convoluted, and in this particular case
we can use a simpler mathematical work-
around that avoids division altogether:

SELECT col1, col2
FROM dbo.T1
WHERE col1 <> 0 and col2 > 2*col1;



I included this example to explain the
unique and important all-at-once opera-
tions concept, and the fact that SQL Serv-
er guarantees the processing order of the
WHEN clauses in a CASE expression.

With the concept of all-at-once in mind,
can you figure out how to write an UP-
DATE statement that swaps the values in
the columns col1 and col2? In most pro-
gramming languages where expressions
and assignments are evaluated in some
order (typically left to right), you need a
temporary variable. However, because in
SQL all assignments take place as if at the
same point in time, the solution is very
simple:

UPDATE dbo.T1
  SET col1 = col2, col2 = col1;
