我在

MySQL的過(guò)程,它有兩個(gè)IN參數(shù)：USERLOGIN(VARCHAR)和的userPassword(VARCHAR),以及兩個(gè)OUT參數(shù)：用戶(hù)ID(INT)和userRights(VARCHAR).

該過(guò)程的工作原理如下：檢查具有給定登錄名和密碼的用戶(hù)是否在數(shù)據(jù)庫(kù)中,如果是,則返回其ID,userRights和設(shè)置.權(quán)限可以連接成一個(gè)字符串,但我想避免連接并隨后解析websettings,因?yàn)閿?shù)據(jù)的結(jié)構(gòu)更復(fù)雜.

現(xiàn)在,我的過(guò)程只返回userID和userRights,如果成功,我運(yùn)行另一個(gè)select語(yǔ)句來(lái)獲取設(shè)置.

目前程序：

DELIMITER $$

CREATE PROCEDURE `proc_login_user`(IN UserName VARCHAR(45), IN Pwd VARCHAR(250), OUT Uid INT, OUT Rights VARCHAR(100))

BEGIN

DECLARE Uname VARCHAR(45);

DECLARE Pass VARCHAR(250);

DECLARE UserId INT;

SET @Uname := UserName;

SET @Pass := Pwd;

SET @UserId = (SELECT ID FROM `users` WHERE Login = @Uname AND Password = @Pass);

SET Uid = @UserId;

SET Rights = /* some SELECT GROUP_CONCAT statement to create string */

END;

我希望在procedure中添加一個(gè)輸出參數(shù)：userSettings,它應(yīng)該是一個(gè)結(jié)果集.

像這樣的東西：

DELIMITER $$

CREATE PROCEDURE `proc_login_user`(IN UserName VARCHAR(45), IN Pwd VARCHAR(250), OUT Uid INT, OUT Rights VARCHAR(100), OUT Settings)

BEGIN

DECLARE Uname VARCHAR(45);

DECLARE Pass VARCHAR(250);

DECLARE UserId INT;

SET @Uname := UserName;

SET @Pass := Pwd;

SET @UserId = (SELECT ID FROM `users` WHERE Login = @Uname AND Password = @Pass);

SET Uid = @UserId;

SET Rights = /* some SELECT GROUP_CONCAT statement to create string */

SET Settings = SELECT * FROM `settings` WHERE UserID = @UserId;

END;

任何幫助,將不勝感激.

謝謝,
