Question

我实际上有两个问题。下面的“Update O”从SQL Server Management Studio（2005）执行得很好，但是从网站（C＃/ ASP.NET）执行时不会运行。我从原始工作代码中唯一的区别是将LEFT命令添加到LEFT（EmployeeBirthdate，4）

这很奇怪，因为第一个查询在网站上运行时运行正常，但第二个查询却没有。

ALTER PROCEDURE [dbo].[ValidateTransfers]
AS
BEGIN
    UPDATE p
    SET DATAREVISIONTYPE = 'Transfer'
    FROM abc as p
    WHERE DATAREVISIONTYPE  = 'Delete' AND
    (SELECT COUNT([OriginalUserId]) FROM abc WHERE DataRevisionType = 'Add' AND FirstName = p.FirstName 
    AND LastName = p.LastName AND EmployeeEmailAddress = p.EmployeeEmailAddress AND EmployeeBirthdate = LEFT(p.EmployeeBirthdate, 4))> 0

    UPDATE O
    SET DATAREVISIONTYPE = 'Modify' FROM abc as O
    WHERE DATAREVISIONTYPE = 'Add' AND
    (SELECT COUNT([OriginalUserId]) FROM abc WHERE DataRevisionType = 'Transfer' AND FirstName = O.FirstName 
    AND LastName = O.LastName AND EmployeeEmailAddress = O.EmployeeEmailAddress AND LEFT(EmployeeBirthdate, 4) = O.EmployeeBirthdate)> 0
END

我的第二个问题是，当我向set命令添加更多集合时，它们实际上并没有更改任何数据。

UPDATE O
SET DATAREVISIONTYPE = 'Modify' 
    O.OriginalUserID = OriginalUserID, 
    O.EmployeeBirthdate = EmployeeBirthdate, 
    O.User_ID = User_ID
FROM abc as O
WHERE DATAREVISIONTYPE = 'Add' AND
(SELECT COUNT([OriginalUserId]) FROM abc WHERE DataRevisionType = 'Transfer' AND FirstName = O.FirstName 
AND LastName = O.LastName AND EmployeeEmailAddress = O.EmployeeEmailAddress AND LEFT(EmployeeBirthdate, 4) = O.EmployeeBirthdate)> 0

提前致谢！

编辑：“修改”背后的逗号来自糟糕的工作副本粘贴。遗憾的是，这不是问题所在。

编辑2：此外，当我单独执行特定查询时，第二个需要大约一分钟才能完成，第一个是静止的。另一方面，如果我突出显示整个存储过程并点击执行，它会立即完成，并且具有与从网站上运行时相同的问题。 IE，正确的记录设置为“转移”但“修改”不起作用

Answer 1

“FROM：”之前还有一个额外的逗号

UPDATE O
SET DATAREVISIONTYPE = 'Modify', FROM abc as O

SQL Server存储过程可以从Mgmt Studio执行，但不能从网站执行
