phpMyAdmin-存储过程中的SELECT语句结果不显示

Question

I Have created a simple procedure:

CREATE PROCEDURE  `simpleProcedure` ( IN  `parameter` INT) NOT DETERMINISTIC READS SQL DATA SQL SECURITY DEFINER 
BEGIN
SELECT * 
FROM table1;    
END

Running this procedure using CALL simpleProcedure(1) in phpMyAdmin does not show the result of the query... How do I make phpMyAdmin show the result of the query inside the procedure?

You need an OUT parameter for it to return results, see http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html .

Example from the sakila database:

DELIMITER $$ 
CREATE DEFINER=`root`@`127.0.0.1` PROCEDURE `film_in_stock`(IN p_film_id INT, IN p_store_id INT, OUT p_film_count INT)
    READS SQL DATA 
BEGIN
     SELECT inventory_id
     FROM inventory
     WHERE film_id = p_film_id
     AND store_id = p_store_id
     AND inventory_in_stock(inventory_id);

     SELECT FOUND_ROWS() INTO p_film_count; 
END$$
