| <div class="block">Checks whether an expression is constant within the GROUP BY clause. If |
| 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. |
