What is a Stored Procedure in SQL Server, and why use it?

A Stored Procedure is a pre-compiled collection of SQL statements and control-of-flow statements stored under a name and processed as a unit in the SQL Server database. Basically, it’s a set of SQL commands that you can call by a simple command.

Below are the reasons why we use stored procedures in SQL Server:

• Performance: SQL Server stores a plan and reuses it, avoiding recompilation.
• Security: Stored Procedures can act as a firewall to your database.
• Reusability and Maintainability: You can use the same Stored Procedure in multiple applications.

How to Create a Stored Procedure in SQL Server

Here’s a simple example to create a Stored Procedure in SQL Server that retrieves all records from an Employee table;

CREATE PROCEDURE sp_GetAllEmployees
AS
BEGIN
    SELECT * FROM Employees;
END;

To execute a SQL Server Stored Procedure, you can use the EXEC keyword:

EXEC sp_GetAllEmployees;

You can also pass parameters into a Stored Procedure. Here’s an example that retrieves employees based on their department:

CREATE PROCEDURE sp_GetEmployeesByDepartment @DepartmentName VARCHAR(50)
AS
BEGIN
    SELECT * FROM Employees WHERE Department = @DepartmentName;
END;

Below is the command to execute the stored procedure.

EXEC sp_GetEmployeesByDepartment 'Engineering';

To modify a Stored Procedure in SQL Server, you can use the ALTER keyword:

ALTER PROCEDURE sp_GetEmployeesByDepartment @DepartmentName VARCHAR(100)
AS
BEGIN
    SELECT * FROM Employees WHERE Department = @DepartmentName;
END;

To delete a Stored Procedure in SQL Server, use the DROP keyword:

DROP PROCEDURE sp_GetEmployeesByDepartment;
