When encountering the error 27000: Triggered Data Change Violation in a Postgres database, follow these steps:
SELECT event_object_table, trigger_name, action_timing, event_manipulation, action_statement
FROM information_schema.triggers;
your_trigger_name with the actual trigger name:SELECT pg_get_triggerdef(pg_trigger.oid)
FROM pg_trigger
JOIN pg_class ON pg_trigger.tgrelid = pg_class.oid
JOIN pg_namespace ON pg_class.relnamespace = pg_namespace.oid
WHERE tgname = 'your_trigger_name';
your_trigger_name and your_table_name with the actual names:ALTER TABLE your_table_name DISABLE TRIGGER your_trigger_name;
Caution: Disabling a trigger should be done with care, as it may have implications on the integrity and logic of your application. Ensure you understand the role of the trigger before disabling it.
ALTER TABLE your_table_name ENABLE TRIGGER your_trigger_name;
Remember, these steps are intended for immediate action. Further analysis and a thorough understanding of the database schema and application logic are necessary for a permanent solution.
