Hi Team,
I have a question about the stored procedure regarding the below code.
USE employees;
DROP PROCEDURE IF EXISTS emp_info;
DELIMITER $$
CREATE PROCEDURE emp_info( IN p_first_name VARCHAR(14), IN p_last_name VARCHAR(16), OUT p_emp_no INTEGER)
BEGIN
SELECT e.emp_no INTO p_emp_no
FROM employees e
WHERE e.first_name = p_first_name and e.last_name = p_last_name;
END$$
DELIMITER ;
 
My Question is how do you invoke the procedure using the CALL syntax. I know how to invoke it using the workbench schema. However, when I tried using the CALL function like this : CALL emp_info (Georgi, Facello), there’s an error code 1318 Incorrect Number of Arguments. I can see that there’re 3 arguments in the procedure, but what should I input in the third argument. Is the third argument @p_emp_no?If so, why is the third argument @p_emp_no?
