the expression completely matches an expression in the GROUP BY clause,
returns true. If the expression is constant within the group, but does
not exactly match, returns false. If the expression is not constant,
throws an exception. Examples:
<ul>
<li>If we are 'f(b, c)' in 'SELECT a + f(b, c) FROM t GROUP BY a', then
the whole expression matches a group column. Return true.
<li>Just an ordinary expression in a GROUP BY query, such as 'f(SUM(a),
1, b)' in 'SELECT f(SUM(a), 1, b) FROM t GROUP BY b'. Returns false.
<li>Illegal expression, such as 'f(5, a, b)' in 'SELECT f(a, b) FROM t
GROUP BY a'. Throws when it enounters the 'b' operand, because it is not
in the group clause.
