Difference between stored procedure and trigger in SQL

In this post, you will understand the difference between the stored procedure and trigger.

The stored procedure has contained a collection of SQL pre-compiled statements to perform the specific task.

CREATE PROCEDURE Procedure_Name
AS
sql_statements
GO;

The trigger is a special kind of store procedure, it invokes only when some events occur in the table, such as Insert, Update, and Delete.

CREATE TRIGGER [schema_name.]trigger_name
ON table_name
AFTER  {[INSERT],[UPDATE],[DELETE]}
[NOT FOR REPLICATION]
AS
{sql_statements}

Procedure	Trigger

Procedure explicitly invoke by using commands like execute	Trigger implicitly invoke when an event occurs in the table, events such as Insert, Update, and delete
The transaction statement, we can add in the stored procedure	The transaction statement we can’t add in the Trigger
Stored Procedure can take input parameters	We can’t pass input parameters to the trigger
Stored Procedure can return the output or values	Trigger can’t return the values
We can call one stored procedure from another procedure – Nesting Procedure	From one trigger we can’t call another trigger – Nesting trigger is not possible
