<p>SELECT statements can appear in expressions as either the
right-hand operand of the IN operator, as a scalar quantity, or
as the operand of an EXISTS operator.
As a scalar quantity or the operand of an IN operator,
the SELECT should have only a single column in its
result.  Compound SELECTs (connected with keywords like UNION or
EXCEPT) are allowed.
With the EXISTS operator, the columns in the result set of the SELECT are
ignored and the expression returns TRUE if one or more rows exist
and FALSE if the result set is empty.
If no terms in the SELECT expression refer to value in the containing
query, then the expression is evaluated once prior to any other


processing and the result is reused as necessary.  If the SELECT expression
does contain variables from the outer query, then the SELECT is reevaluated
every time it is needed.</p>

<p>When a SELECT is the right operand of the IN operator, the IN
operator returns TRUE if the result of the left operand is any of
the values generated by the select.  The IN operator may be preceded
by the NOT keyword to invert the sense of the test.</p>
