Please note that merge/delete action may fail because of limitations caused by other objects such as foreign keys, existing data and so on. Please check the merge execution result for details.

Column Extra for columns can have one of two things: AUTO_INCREMENT or ON UPDATE rule. If the column is AUTO_INCREMENT and selected to be merged, then the generated merge statement has PRIMARY KEY included even if it is not selected in Constraints, because auto-increment can not be specified without a key.
