SQL Server 存储过程从 Mgmt Studio 可以正常执行，但不能从网站执行

Question

我实际上有两个问题。下面的“更新 O”在 SQL Server Management Studio (2005) 中执行良好，但在从网站 (C#/ASP.NET) 执行时不运行。我与原始工作代码的唯一区别是将 LEFT 命令添加到 LEFT(EmployeeBirthdate, 4)

这很奇怪，因为第一个查询在通过网站运行时运行良好，但第二个却没有。

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”后面的逗号来自糟糕的复制粘贴工作。不幸的是，这不是问题所在。

编辑 2：此外，当我单独执行特定查询时，第二个查询大约需要一分钟才能完成，而第一个查询是即时的。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，并且会出现与从网站运行相同的问题。 IE，正确的记录设置为“转移”，但“修改”不起作用

Answer 1

“FROM:”前多了一个逗号

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