编辑4/18： 我要感谢迄今为止回答过的所有人。作为一项测试，我已经建立了一个新工作，其中只有一步，
EXECUTE p_CallLog_GetAbandonedCallsForCallList
此过程本身运行正常并且不报告任何错误或警告，但在作为作业的一部分执行时不会运行。我在运行作业时收到的错误是：
Executed as user: NT AUTHORITY\SYSTEM. OLE DB provider 'SQLOLEDB' reported an error. [SQLSTATE 42000] (Error 7399) [SQLSTATE 01000] (Error 7312) OLE DB error trace
[OLE/DB Provider 'SQLOLEDB' IDBInitialize::Initialize returned 0x80004005: ].
[SQLSTATE 01000] (Error 7300). The step failed.
我尝试将运行更改为用户选择，我尝试的每个其他选项都会导致错误：
Executed as user: Db2WebCal. Remote access not allowed for Windows NT user activated
by SETUSER. [SQLSTATE 42000] (Error 7410). The step failed.
我尝试过的所有用户都在链接服务器上进行了本地登录设置。

ORIGINAL： 我有以下存储过程用于使用值填充表。
PROCEDURE [dbo].[p_OutboundCallList_Create]
AS
BEGIN
TRUNCATE TABLE T_OutboundCallList
EXECUTE p_LeadVendor_GetCallsForCallList
EXECUTE p_CallCampaign_GetCallsForCallList
EXECUTE p_CallLog_GetAbandonedCallsForCallList
EXECUTE p_NoSaleFollowUp_GetCallsForCallList
END
运行此工作正常，表填充。创建作业并添加以下步骤后：
EXEC p_OutboundCallList_Create
作业失败，并显示以下错误消息：
Executed as user: NT AUTHORITY\SYSTEM. Warning: Null value is eliminated
by an aggregate or other SET operation. [SQLSTATE 01003] (Message 8153)
Warning: Null value is eliminated by an aggregate or other SET operation.

如果我注释掉该行
EXECUTE p_CallLog_GetAbandonedCallsForCallList
..工作顺利。这个存储过程（p_CallLog_GetAbandonedCallsForCallList）确实依赖链接服务器并且运行良好，并且在运行p_OutboundCallList_Create时运行正常。它只会在我作为工作的一部分运行时失败。我尝试以不同的用户身份运行（sa，benderle等）并始终获得相同的结果（失败）。
答案 0 :(得分：0)
“通过聚合或其他SET操作消除空值”是SQL Server警告，这意味着如果运行查询并且引发此警告，则不会在输出中看到它（切换到“消息” SQL Server Management Studio中的选项卡以查看此内容。）
虽然这是一个警告，但可能是SQL作业中的任何警告都会导致作业出错。修复p_CallLog_GetAbandonedCallsForCallList程序，使其不会发出警告，并且您的工作将按预期工作。
答案 1 :(得分：0)
我很想看到p_CallLog_GetAbandonedCallsForCallList中的代码，因为它可以解释为什么用户NT AUTHORITY \ SYSTEM会发生这种情况。
当您对其中包含空值的数据集执行聚合（例如sum()，max()，count()时，会出现此消息。）
要解决此问题，您可能需要在相关字段周围放置一个ISNULL（），或者使用INNER JOIN而不是LEFT或RIGHT JOIN。
