Stored Procedures in SQL Server

Introduction:

A collection of SQL statements is referred to as a stored procedure in SQL and is stored together in a database. It can execute one or more DML operations on the database and return value, if any, depending on the statements in the procedure and the arguments you pass. As a result, it enables reuse by allowing you to pass the same statements more than once.

In simple words, a SQL Server stored procedure is a collection of statements stored in the database as a logical unit.

Benefits:

Multiple users or different client apps can use stored procedures to execute code without having to rewrite it. Because stored procedures prevent direct access to the tables, the risk is minimized.

Additionally, to prevent source code from being seen inside the stored procedures, we can encrypt them as we create them. When the SQL Server stored procedure is initially run, a plan is created and stored in the buffer pool so that it can be used the next time it is run. This means, stored procedures are created once and stored in executable form, they may be called quickly and effectively. Therefore, the response is prompt. The automated caching of the executable code reduces the memory requirements.

You can reduce redundant coding and boost efficiency by structuring your apps around a shared set of stored procedures. By separating application processing from server-side logic, stored procedures improve scalability.

Syntax:

CREATE PROCEDURE <ProcedureName>
AS
BEGIN
<…Statements…>
END

To execute the stored procedure.

EXEC <ProcedureName>;

Example:

CREATE PROCEDURE uspGetOrdersInfo
AS
SELECT * FROM tbOrders WHERE Status = ‘PLACED’
GO;

EXEC uspGetOrdersInfo;
