MySQL Error 4110: Altering Invisible PK Column
Description
This error indicates an attempt to modify a generated invisible primary key (GIPK) column, which MySQL automatically creates and manages. It occurs when a user tries to alter a column like 'my_row_id' that MySQL uses internally, typically when the `sql_generate_invisible_primary_key` system variable is enabled.
Error Message
Altering generated invisible primary key column 'my_row_id' is not allowed.
Known Causes
3 known causesDirect Alteration Attempt
You explicitly executed an `ALTER TABLE` statement targeting the generated invisible primary key column, such as `my_row_id`.
Automated Schema Management
An ORM, migration tool, or other automated script attempted to modify the table schema, inadvertently including the GIPK column.
Misunderstanding GIPK Role
