This would happen in an UPDATE using MERGE statement.
The cause of this that the Inner query in MERGE ( the one
after USING clause ) returns duplicate rows and Oracle
doesnt know which value to consider for UPDATE.
The only probable solution is to remove the duplicates from
the query or strengthen the join ( ON Clause ) so that the
unique values are considered for update.
