Oracle : Ошибка 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 which
had not been merged because the view used syntax (for example,
DISTINCT or GROUP BY) preventing the merge, or because of
initialization file parameter settings.
*Action: Determine the reason the view will not merge and, if possible,
make changes so that it can.
