You attempted to use an aggregate function inappropriately. For example, a SELECT statement cannot contain an aggregate function within a predicate in the WHERE clause unless the aggregate function constitutes an outer reference. Other invalid uses include specifying an aggregate function in the SET clause of an UPDATE statement, or using an aggregate function in a CHECK constraint.
