HAVING clause
The HAVING clause places conditions on results created by an aggregate operation on groups.
The HAVING clause must follow the GROUP BY clause and precede the ORDER BY clause.
The WHERE clause filters rows based on specified conditions before the aggregate operation.
The HAVING clause filters rows based on specified conditions after the aggregate operation has taken place.
