How to Convert Your SQL Code into a Stored Procedure in MySQL

If you're working with MySQL and seek to encapsulate your SQL queries into a reusable block of code, you might consider creating a stored procedure. Stored procedures can help streamline and optimize your database operations by wrapping complex logic into a callable object.

What is a Stored Procedure?

A stored procedure is a precompiled collection of one or more SQL statements, stored under a name and processed as a unit. They enhance efficiency and security by allowing reusable, encapsulated code within the database.

Steps to Create a Stored Procedure

Here's how you can convert your SQL code into a proper stored procedure with correct syntax in MySQL.

Explanation

DELIMITER: Changes the default delimiter from ; to // to allow the use of semicolons within the procedure body.

CREATE PROCEDURE: Starts the declaration of a stored procedure. GetEmployeesByDept is the procedure name.

IN dept_id INT: Declares an input parameter dept_id of type INTEGER.

BEGIN ... END: Encapsulates the procedure's SQL statements.

Calling the Stored Procedure

To call the stored procedure, use the CALL statement:
