You're on a roll — The error ERROR 3108 (HY000): Column 'HireDate' has a generated column dependency means that another column in your table, BonusMonth, is calculated based on the HireDate column. MySQL does not allow you to directly rename a column that is part of a generated column's definition. To fix this, you need to: 1. Drop the generated column (BonusMonth). 2. Rename the HireDate column to DOE. 3. Re-add the BonusMonth column with its generated definition, referencing the new DOE column. Assuming BonusMonth is generated from the month of HireDate, here are the steps: Step 1: Drop the BonusMonth column. ALTER TABLE Employee DROP COLUMN BonusMonth; Step 2: Rename the HireDate column to DOE. ALTER TABLE Employee RENAME COLUMN HireDate TO DOE; Step 3: Re-add the BonusMonth column as a generated column, using the new DOE column. ALTER TABLE Employee ADD COLUMN BonusMonth INT GENERATED ALWAYS AS (MONTH(DOE)) STORED; After executing these three commands in sequence, the HireDate column will be renamed to DOE, and BonusMonth will continue to be a generated column based on DOE.
