phpMyAdmin的 - 在存儲過程中的SELECT語句的結果沒有顯示

Question

我創建了一個簡單的程序：

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

使用運行在phpMyAdmin CALL simpleProcedure(1)不顯示查詢的結果這個程序......我如何phpMyAdmin的在過程中顯示查詢的結果？

您需要一個OUT參數爲它返回結果，請參閱http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html。

從sakila數據庫實例：

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$$
