How to Delete a Stored Procedure in SQL Server: Step-by-Step Guide

What Is a Stored Procedure?

Before we jump into the “how to delete a store procedure in SQL Server” we must know “what is store procedure”. A store procedure in SQL saves the group of multiple SQL queries that you can call whenever needed. It saves the time to write the same SQL query every time.

Example:

CREATE PROCEDURE GetEmployeeDetails
AS
BEGIN
    SELECT * FROM Employees
END

This small procedure is written to fetch all records from Employee table. Now, you don’t require this procedure and want to delete it.

Things to Do Before Deleting a Stored Procedure

Deleting a Stored Procedure might seem like a very simple task, but there are a few things to check before performing delete operation. It’s kind of like making sure the lights are off before leaving the house.

1. Backup Your Database: This is an important and safer step, if you have deleted a procedure mistakenly, you have a chance to get the procedure from backup.
2. Check for Dependencies: Make sure no other part of your system relies on the stored procedure you are deleting.
3. Review the Code: Take a quick look at the stored procedure’s script. You might realize it’s still useful or at least worth saving for reference.
