          Description

          ERROR 1903 (HY000): Primary key cannot be defined upon a computed column .

          Virtual column was a nice way to remove stuff like
          PRIMARY KEY (`COD_INV`, `COD_FAM`, `COD_MAG`, `COD_FIL`, `COD_ID_INV`)

          • It's a bad practice to use triggers
          • It's a bad practice to use hidden primary key ,
          • It's a bad practice to use virtual column .

          What could we advice that can be transparent to the application layer to fixe such bad design for InnoDB.

          Rewrite the application is not always a political correct answer.
