Question

我在MySQL中遇到一个让我疯狂的错误，我无法弄清楚是什么问题。我做了以下电话：

CALL ProfileUpdateProgress(107)

MySQL返回错误：“ FUNCTION ccms.fnGetProfileAlbumsPhotoCount的参数数量不正确;预期为2，得到1 ”

现在，正如您在下面的代码中看到的那样，对该函数的调用是：fnGetProfileAlbumsPhotoCount（_profileId，profileUserId）

这两个论点不是吗？为什么会出错？我疯了!!

数据库过程：

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 ;

反过来调用：

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 ;

并调用错误的函数：

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 ;

啊终于解决了。选择列中另一个名为fnUserGetChildrenProfileCount的函数是罪魁祸首，因为它也调用了fnGetProfileAlbumsPhotoCount（）函数，并且该调用只有一个参数，即缺少第二个参数。
