MySQL Error 1435: Trigger Schema Mismatch
Description
This error indicates that a trigger definition refers to a database object (like a table) that resides in a different schema than the trigger itself, or that the trigger is being created in a schema where its definition is invalid. It typically occurs when the current database context or the explicit schema qualification within the trigger's code does not align with the intended database for the trigger's operations.
Error Message
Trigger in wrong schema
Known Causes
4 known causesCross-Schema Object Reference
A trigger is defined in one schema but attempts to operate on a table located in a different schema without explicitly qualifying the table name with the correct schema.
Incorrect Database Context
The `USE database_name;` statement points to a different schema than where the trigger expects to operate, leading to a mismatch in the current database context.
Migration or Restore Issues
During a database migration or restore, a trigger might be applied to a schema where its original schema qualifications no longer apply or are misinterpreted.
Explicit Schema Mismatch in Definition
The trigger's `FOR` clause or body explicitly specifies a schema for a table that differs from the schema where the trigger is being created.
