The output Records: 10 Duplicates: 0 Warnings: 0 indicates that the ALTER TABLE command itself did not create any duplicate rows. The "Out of range" error means that the value you tried to put into the BonusMonth column (likely the full HireDate) was not a valid integer for that column.
To "start over" and correctly add the BonusMonth column, follow these steps:
Step 1: Remove the BonusMonth column if it was partially added or added incorrectly.
ALTER TABLE Employee DROP COLUMN BonusMonth;
Step 2: Add the BonusMonth column correctly, extracting only the month from HireDate.
ALTER TABLE Employee ADD COLUMN BonusMonth INT AS (MONTH(HireDate)) STORED;
Step 3: Verify that the BonusMonth column was added successfully and check its data type.
DESCRIBE Employee;
This command will display the structure of the Employee table, including all column names, their data types, and other properties. You should see BonusMonth listed as an INT type.
