Triggers in SQL Part 2 (Hindi)

Описание: Triggers in SQL Part 2 (Hindi) allows you to perform any operation at the occurrence of an event.
A SQL trigger is a special type of stored procedure that automatically executes whenever an event occurs in the database server. Triggers are used to maintain the integrity of the data and implement business rules whenever data is added, modified, or deleted.

SQL triggers are usually associated with a table or view and are fired when a specific operation, such as an INSERT, UPDATE, or DELETE statement, is executed on the table or view. When the trigger is fired, the trigger code is executed. This code can be used to perform tasks such as validating data, performing calculations, or modifying other data.
