Explain about triggers


A database trigger is stored code that is executed immediately after a predefined event. It is used to ensure the coordinated performance of related actions. Although implementation varies, all major relational databases support triggers.

 

A database trigger is procedural code that is automatically executed in response to certain events on a particular table in a database. Triggers can restrict access to specific data, perform logging, or audit data modifications.
