phpMyAdmin-存儲過程中的SELECT語句結果不顯示

Question

我創建了一個簡單的過程：

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

使用phpMyAdmin中的CALL simpleProcedure(1)運行此過程不會顯示查詢結果...如何使phpMyAdmin在過程中顯示查詢結果？

您需要一個OUT參數來返回結果，請參見http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html 。

sakila數據庫中的示例：

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$$
