What is a Stored Procedure?

A pre-written SQL query that can be called more than once and still execute the same way is called a Stored Procedure. For example, we can design a stored procedure in an SQL database to insert, select, and update data. Parameters can also be passed to the stored routines.

A stored procedure in MySQL can be called with a SELECT statement to run the procedure and get its output. This is helpful if you want to run a procedure that returns a result set or use the output of a stored process in a query.

You use the CALL statement followed by the procedure name and any required parameters to call a stored procedure using a SELECT statement. You can call the procedure and obtain its results as if they were a table by using the SELECT statement enclosed in parenthesis if the procedure returns a result set.

Here are four typical methods and examples for each:

• Call Stored Procedure Without Parameters
• Using SELECT With Input Parameters
• Using SELECT With Output Parameters
• Using SELECT With Input and Output Parameters

Stored procedures in MySQL are powerful tools for encapsulating SQL logic and enabling reusability. However, executing stored procedures via SELECT statements can provide additional flexibility, especially when integrating their results directly into queries.

This article explores various methods of calling stored procedures using SELECT statements in MySQL, covering scenarios with and without parameters. By understanding these techniques, database developers can enhance the efficiency and versatility of their SQL workflows, ensuring smoother data management processes.
