<p>^A [SELECT] statement enclosed in parentheses may appear as a scalar
quantity. ^A [SELECT] used as a scalar quantity must return a result set
with a single column. ^The result of the expression is the value of the
only column in the first row returned by the SELECT statement. ^If the SELECT 
yields more than one result row, all rows after the first are ignored. ^If
the SELECT yields no rows, then the value of the expression is NULL.
^(The LIMIT of a scalar subquery is always 1.
Any other LIMIT value given in the SQL text is ignored.)

<p>^All types of [SELECT] statement, including aggregate and compound SELECT
queries (queries with keywords like UNION or EXCEPT) are allowed as scalar
subqueries.
