ORA-02292: Integrity constraint violated - child record found
What it means
A DELETE (or key UPDATE) of a parent row is blocked because child rows still reference it.
How to fix it
Delete the child rows first, or define the foreign key with ON DELETE CASCADE / SET NULL if that is the intended behaviour. The message names the foreign key constraint so you can find the child table.
