PLS-00117: Duplicate connect-by clause in table expression



PLS-00117: Duplicate connect-by clause in table expression..

Answer / guest

Cause: Two or more CONNECT BY clauses were found in a SELECT
statement. The CONNECT BY clause defines a relationship used
to return rows in a hierarchical order. The relationship can
contain two expressions separated by a relational operator
(such as = or !=), but a statement can contain only one
CONNECT BY clause.

Action: Remove one of the CONNECT BY clauses and, if
necessary, separate expressions by a relational operator.
