Oracle Database / SQL & PL/SQL Errors
ORA-02292: handle dependent child records before a parent delete
A parent deletion may be blocked because related rows still exist. Determine the business relationship before suggesting cascading deletion.
Environment and inputs: Oracle Database 19c baseline · SQL*Plus-compatible SQL unless RMAN, DGMGRL, ADRCI or a host shell is specified. Check release, patch level, edition and container first.
Start with this diagnostic
Use the stated SQL, RMAN, DGMGRL or host shell and replace sample names with approved targets. DBA and V$ views need authorized catalog access in the correct container. Do not grant broad privileges for an example.
SELECT owner, constraint_name, table_name, delete_rule FROM all_constraints WHERE owner = 'APP_OWNER' AND constraint_name = 'FK_ORDER_CUSTOMER';Read the result
The constraint metadata identifies the child table and configured delete behavior. It does not authorize removal of the dependent business data.
Resolve and verify
Have the application owner inspect dependent records and select an approved retention or archival workflow. Retest with representative relationships in a safe environment.
Operational precautions
Do not add ON DELETE CASCADE or disable the constraint without reviewing the full data lifecycle.
