| ERROR | Duplicate having-clause in table expression |
| CAUSE | Two or more HAVING clauses were found in a SELECT statement. The HAVING clause specifies a condition under which groups of rows (formed by the GROUP BY clause) are included in the result. The condition can include several logical expressions connected by AND or OR, but a statement can contain only one HAVING clause. |
| ACTION | Remove one of the HAVING clauses and, if necessary, connect logical expressions by AND or OR. |
