我想传入一个int值并得到一个短密码列表,短密码小于这个int值。我在修改MySQL游标时遇到了问题,例如:http://dev.mysql.com/doc/refman/5.0/en/cursors.html。我想用短密码打印出行,但是任何时候只要结果有多行PhpMyAdmin就无限期地显示“处理请求”。我做错什么了?它毁了我周六的工作效率!
DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `ShortPasswd`(IN `passwordLength` TINYINT)
BEGIN
DECLARE done INT DEFAULT FALSE;
DECLARE a INT;
DECLARE b VARCHAR(255);
DECLARE cur1 CURSOR FOR SELECT UID, Password
FROM authentication WHERE CHARACTER_length(Password) < passwordLength;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
OPEN cur1;
read_loop: LOOP
FETCH cur1 INTO a, b;
IF done THEN
LEAVE read_loop;
END IF;
SELECT b;
END LOOP;
CLOSE cur1;
END
$$
DELIMITER ;
最佳答案
DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `ShortPasswd`(IN `passwordLength` TINYINT)
BEGIN
SELECT UID, Password
FROM authentication WHERE CHARACTER_length(Password) > passwordLength;
END
$$
DELIMITER ;
您将直接获得行UID和密码。当您从查询中得到
call ShortPasswd;
