How does MySQL execute stored procedures?
The steps for executing a stored procedure in MySQL are as follows:
- To create a stored procedure, you first have to use the CREATE PROCEDURE statement to define parameters, execution logic, and other details.
DELIMITER //
CREATE PROCEDURE my_procedure (IN param1 INT)
BEGIN
SELECT * FROM my_table WHERE column = param1;
END //
DELIMITER ;
- Call the stored procedure by using the CALL statement and passing in the parameters.
CALL my_procedure(123);
- To view stored procedures: You can use the SHOW CREATE PROCEDURE statement to see the definition of the stored procedures that have already been created.
SHOW CREATE PROCEDURE my_procedure;
- To remove a stored procedure, you can use the DROP PROCEDURE statement.
DROP PROCEDURE my_procedure;
By following the above steps, you can create, call, and manage stored procedures in MySQL.
