SQL And Beyond: Stored Procedures

What is a Store Procedure?

A stored procedure is a set of one or more SQL statements or procedural logic stored in a database management system (DBMS). These set of SQL statements can executed multiple times without recompilation.

Why do we need a Stored Procedure?

Stored procedures offer various benefits, including:

• Reusability: As I mentioned before, Stored procedures can be utilized and reused by multiple users and applications through a simple call.
• Security: You can restrict the users from direct access to the table using stored procedures
• Low network traffic: The server only passes the procedure name instead of the whole query, reducing network traffic.
• Performance increase: After the initial execution, a plan for the stored procedure is generated and cached in the buffer pool, results faster executions next time

If stored procedures and functions are similar, when exactly should we use each of them?

Stored procedures and functions may appear similar in terms of concepts, but each has its own distinct usage:

How do I create and use a store procedure?

Key Takeaways:

A stored procedure is a precompiled set of one or more SQL statements or procedural logic stored in a database management system (DBMS). It can be executed multiple times to perform a specific task or series of tasks within the database. Stored procedures are designed to reduce network traffic, enhance performance, and contribute to maintaining database integrity.
