Description: The keyword ‘AFTER’ in SQL is used in the context of triggers, which are stored procedures that automatically execute in response to certain events in a database. Specifically, ‘AFTER’ is employed to indicate that the trigger should activate after a data modification operation, such as an insert, update, or delete, has been completed. This feature is essential for ensuring that the actions defined in the trigger are performed once the main operation has finished, allowing for the maintenance of data integrity and the execution of additional tasks, such as audits or updates in other tables. The use of ‘AFTER’ enables database developers to implement complex logic and automate processes, thereby enhancing efficiency and consistency in data management. In summary, ‘AFTER’ is a powerful tool in the SQL arsenal that allows database administrators and developers to manage events effectively and in a controlled manner.
