MySQL Error 4108: Invisible Primary Key Column Exists
Description
This error occurs when MySQL attempts to automatically generate an Invisible Primary Key (GIPK) column named 'my_row_id' for a table, but a column with that exact name already exists. It typically indicates a conflict between the automatic GIPK generation setting and existing table schema or an explicit column definition.
Error Message
Failed to generate invisible primary key. Column 'my_row_id' already exists.
Known Causes
3 known causesGIPK Setting Conflict
The `sql_generate_invisible_primary_key` server variable is enabled, and you are creating a table that already contains a column named 'my_row_id'.
Schema Import Collision
Attempting to import a table schema or data that includes a column named 'my_row_id' into a MySQL instance with `sql_generate_invisible_primary_key` enabled.
Manual Table Definition Clash
You explicitly defined a column named 'my_row_id' in a `CREATE TABLE` or `ALTER TABLE` statement while the GIPK feature is active, leading to a naming clash.
