What is a Trigger in SQL?

Answer 1

A Trigger in SQL is a stored database procedure that automatically gets invoked when any special event occurs in the database. They can be invoked when you insert or update any set of rows or columns. The trigger can be executed before or after the execution of the SQL statement. The before triggers run the action of the trigger before running the triggering statement. The after triggers, on the other hand, run the action of the trigger after running the triggering statement.
