PLS-00118

Error: PLS-00118: Duplicate group-by clause in table expression

Causa: Two or more GROUP BY clauses were found in a SELECT statement. The GROUP BY clause lists column expressions used to form a summary row for each group of selected rows. The list can contain several column expressions separated by commas, but a statement can contain only one GROUP BY clause.

Acción: Remove one of the GROUP BY clauses and, if necessary, separate column expressions by commas.
