PostgreSQL Error 23001: Restrict Violation on Deletion
Description
This error indicates an integrity constraint violation, specifically a 'restrict violation.' It commonly occurs when attempting to delete a row from a parent table that still has dependent rows in a child table, and the foreign key constraint is defined with `ON DELETE RESTRICT`. PostgreSQL prevents the deletion to maintain data integrity.
Error Message
restrict violation
Known Causes
3 known causesParent Row Has Dependent Children
You attempted to delete a row from a parent table, but one or more rows in a child table still reference it via a foreign key with `ON DELETE RESTRICT`.
Foreign Key `ON DELETE RESTRICT` Setting
The foreign key constraint between the tables is explicitly configured with `ON DELETE RESTRICT`, which disallows deletion of parent rows if child rows exist.
Unawareness of Data Dependencies
The deletion attempt was made without prior knowledge or verification of existing dependent records in related tables, leading to the violation.
