In this article, we will see the difference between Stored Procedure and Trigger in SQL. Following are the main differences between Stored Procedure and Trigger:
| Stored Procedure | Trigger |
|---|---|
| Store Procedures are invoked explicitly | Triggers are invoked implicitly |
| Stored procedure is a user defined piece of code which may return a value (making it a function) that is invoked by calling it explicitly. | A trigger is a stored procedure that runs automatically when various events happen (eg update, insert, delete). |
| We can execute a stored procedure whenever we want | Trigger can only be executed whenever an event (insert, delete, and update) is fired on the table on which the trigger is defined |
| Stored procedure can take input parameters | We can’t pass parameters as input to a trigger. |
| We can use transaction statements like begin transaction, commit transaction, and rollback inside a stored procedure | We cant use transaction statements inside a trigger |
| We can call a stored procedure from the front end | We cant call trigger from front end |
