What is creating a stored procedure in MySQL?

Creating a stored procedure in MySQL is a way to encapsulate a set of SQL statements that can be executed as a single unit. This is particularly useful for reducing code duplication and making complex database operations easier to manage. Stored procedures can accept parameters, can be reused, and can improve performance by reducing the amount of data sent between the application and the database.

A stored procedure is defined with the `CREATE PROCEDURE` statement, followed by the procedure name and its parameters. After that, the SQL statements that make up the procedure are included within the procedure body.

Here is an example of a simple stored procedure that retrieves employee details by their ID:

DELIMITER // CREATE PROCEDURE GetEmployeeByID(IN emp_id INT) BEGIN SELECT * FROM employees WHERE id = emp_id; END // DELIMITER ;
