PostgreSQL Error 27000: Triggered Data Violation
Description
This error indicates that a data modification operation (INSERT, UPDATE, DELETE) violated a condition enforced by a database trigger. The trigger's logic explicitly prevented the change to maintain data integrity or enforce specific business rules.
Error Message
triggered data change violation
Known Causes
4 known causesTrigger Logic Conflict
A BEFORE or AFTER trigger function detected that the proposed data change would violate a defined business rule or data integrity constraint, and raised an error.
Conflicting Data Constraints
The data change, while seemingly allowed, might indirectly violate another constraint (e.g., FOREIGN KEY, CHECK) that a trigger is designed to protect or enforce, leading to the violation.
Recursive Trigger Issues
A chain of triggers or a recursive trigger might lead to a state where a subsequent trigger detects an invalid data condition and prevents the operation.
External System Data Rules
The trigger might be enforcing complex data validation rules derived from an external application or system, which the proposed change contradicts.
