帮助的参数不正确的MySQL号功能的错误
问题描述:
我得到在MySQL是推动我疯了,我只是无法弄清楚什么是错的错误。我让下面的调用:帮助的参数不正确的MySQL号功能的错误
CALL ProfileUpdateProgress(107)
的MySQL返回错误:“为功能ccms.fnGetProfileAlbumsPhotoCount参数数目不正确;预计2,有1”
现在,你可以在代码中看到下面,呼叫被该功能做的是:fnGetProfileAlbumsPhotoCount(_profileId,profileUserId)
这两个参数是不是?为什么错误? 我要疯了!
数据库特效:
DELIMITER $$
DROP PROCEDURE IF EXISTS `ProfileUpdateProgress` $$
CREATE DEFINER=`root`@`%` PROCEDURE `ProfileUpdateProgress`(
IN _profileId integer
)
BEGIN
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
CALL ProfileUpdateProfileProgress(_profileId);
END $$
DELIMITER ;
进而调用:
DELIMITER $$
DROP PROCEDURE IF EXISTS `ProfileUpdateProfileProgress` $$
CREATE DEFINER=`root`@`%` PROCEDURE `ProfileUpdateProfileProgress`(IN _profileId int)
BEGIN
-- Declarations here
SELECT profileEyes, profileSex, profileHair, profileBustBand, profileBustCup, profileBirthCountry, profileProfession , profileAbout,
profileBiography, fnGetProfilePhoto(_profileId, null) AS profilePhoto, fnGetProfileAlbumsPhotoCount(_profileId, profileUserId) AS albumPhotoCount,
userAllowMultipleProfiles, profileIsPrimary, fnUserGetChildrenProfileCount(userId) AS ownerProfileCount
INTO _profileEyes, _profileSex, _profileHair, _profileBustBand, _profileBustCup, _profileBirthCountry, _profileProfession,
_profileAbout, _profileBiography, _profilePhoto, _albumPhotoCount, _userAllowMultipleProfiles, _profileIsPrimary,
_ownerProfileCount
FROM profile
INNER JOIN user
ON profileUserId = userId
WHERE profileId = _profileId;
-- Other irrelevant code here
END $$
DELIMITER ;
和被调用的函数的错误看起来像:
DELIMITER $$
DROP FUNCTION IF EXISTS `fnGetProfileAlbumsPhotoCount` $$
CREATE DEFINER=`root`@`%` FUNCTION `fnGetProfileAlbumsPhotoCount`(
_profileId int,
_userId int
) RETURNS int(11)
BEGIN
DECLARE outProfileAlbumsPhotoCount int DEFAULT 0;
-- Irrelvant Code
RETURN outProfileAlbumsPhotoCount;
END $$
DELIMITER ;
答
啊终于解决了这个问题。另一个在select列中调用fnUserGetChildrenProfileCount的函数是罪魁祸首,因为它也调用了fnGetProfileAlbumsPhotoCount()函数,THAT调用只有一个参数,即错过了第二个参数。
你能直接从MySQL客户端调用`fnGetProfileAlbumsPhotoCount`吗? – gregjor 2011-01-22 09:33:12
