Ora-02014

Question

Is there any workaround available with ora-02014? I have a view that contains left outer join with "INSTEAD UPDATE" trigger on it. UPDATE VIEW SET... WHERE... goes well, but SELECT ... FOR UPDATE causes ORA-02014. Any suggestions?

First I thought thats a bug, that's why I asked you for the version number.
But the error description states it clearly. Your are not allowed to use outer joins in select for update queries.
ORA-02014 cannot select FOR UPDATE from view with DISTINCT, GROUP BY,etc.
Cause: An attempt was made to SELECT... FOR UPDATE from a view whose
defining SELECT statement uses at least one of the following constructs in its
outer block: outer join, GROUP BY clause, aggregate functions, SELECT DISTINCT,
CONNECT BY clause, or set operation, UNION, INTERSECT, or MINUS.
Action: Do not use SELECT... FOR UPDATE on this view.
****************************************************************************** Oracle can't determine which rows need to be locked.
And the instead of trigger won't fire at this time, because your are selecting and not updating
