Answer:
ALTER TABLE orders
MODIFY (amount DEFAULT 250)
Explanation:
- ALTER TABLE statement is used to modify "amount" column in the existing "orders" table
- MODIFY (amount DEFAULT 250) is used to set the default value 250 of the "amount" column.
Therefore if the supervisor wants the amount column to be configured to accept a default value of 250, then "ALTER TABLE orders MODIFY (amount DEFAULT 250) " statement should be issued.
