You can use aggregate operators in a HAVING condition.
You cannot specify BLOB, CLOB, UDT, or Period columns in the HAVING condition.
You cannot specify a SAMPLE clause within a subquery predicate within a HAVING clause.
HAVING condition filters rows from a single group defined in the select expression list that has only aggregate results, or it selects rows from the group or groups defined in a GROUP BY clause.
