MySQL Error 3059: REPLACE on View Fails
Description
Error 3059 indicates that a `REPLACE` statement cannot be executed on a database `VIEW`. This occurs when the `VIEW` does not expose all the necessary underlying table columns, such as primary keys or unique indexes, that `REPLACE` requires to identify and delete existing rows before inserting new ones. Consequently, MySQL cannot perform the implicit `DELETE` operation because the rows it needs to access are not directly visible or manipulable through the view's definition.
Error Message
REPLACE cannot be executed as it requires deleting rows that are not in the view
Known Causes
3 known causesView Lacks Key Columns
The view definition omits the primary key or unique index columns from the underlying base table, which are crucial for `REPLACE` to identify and delete rows.
Non-Updatable View
The view itself is not updatable due to its definition (e.g., complex joins, aggregate functions, or distinct clauses), preventing DML operations like `REPLACE`.
Complex View Logic
The view is based on multiple tables or contains complex logic that makes it impossible for MySQL to unambiguously determine which specific rows in the underlying tables should be deleted or modified.
