MariaDB Error 1465: Cannot Create Triggers on System Tables
Description
Error 1465 indicates an attempt to create a database trigger on a system table within MariaDB. System tables, such as those in `mysql` or `information_schema` databases, are critical for the database's internal operations and are protected from user-defined triggers to ensure stability and data integrity. This error commonly arises during schema migrations or administrative tasks that try to apply triggers across all tables without excluding system schemas.
Error Message
Triggers can not be created on system tables
Known Causes
3 known causesAccidental System Schema Targeting
SQL scripts or commands designed to apply triggers broadly might inadvertently include system databases (e.g., `mysql`, `information_schema`, `performance_schema`) in their scope.
Lack of Awareness of System Table Protection
Users or developers might be unaware that MariaDB, like other relational databases, restricts modifications such as triggers on its internal system tables to prevent corruption or instability.
Incorrect Database/Schema Selection
The `USE` statement or fully qualified table name in the `CREATE TRIGGER` command might mistakenly point to a system table instead of an intended user-defined table.
