SQL Trigger是更新随机行而不是连接行

Question

我在更新触发器中有此查询

UPDATE [FSSQLPROD01].[collectionsDELETE].[dbo].[collections] 
SET 
    Defendant_1 = i.DisplayName 
    , Loan_Number_1 = i.Comments 
    , Client = i.KS_BookName 
    , Date_Instructed = i.OpenDate 
    , Person_Responsible_name = i.ResponsibleFeeEarnerName 
    , Person_Responsible_Email = i.ResponsibleFeeEarnerEmail 
    , Person_Acting_name = i.BillingFeeEarnerName 
    , Person_Acting_email = i.BillingFeeEarnerEmail 
    , Agent_Acting_name = i.BillingFeeEarnerName 
    , Agent_Acting_email = i.BillingFeeEarnerEmail 
    , CBA_Panel_Service_Area = i.KS_ServiceCat 
    , HBN_Number = i.KS_ClientAcctRef 
    , St_George_Contact = i.KS_Instructor 
FROM 
    [FSSQLPROD01].[collectionsDELETE].[dbo].[collections] c
INNER JOIN 
    Inserted i
ON
    Left(c.file_number, 6) COLLATE DATABASE_DEFAULT = i.MatterNumber COLLATE DATABASE_DEFAULT

现在，Join连接在File_Number上匹配，例如70003-1但由于某些未知原因，应该更新到此行的数据已更新为一个非常随机的行614864-7

我可以继续执行触发器并尝试更新70003-1行，但我继续更新另一行614864-7

这也在链接服务器上运行，触发器位于一台与其他服务器约会的服务器上

服务器tigger位于Microsoft SQL Server 2005上 - 9.00.3042.00（X64）2007年2月10日00:59:02版权所有（c）1988-2005 Microsoft Corporation企业版（64位）在Windows NT 5.2上（Build 3790： Service Pack 2）

服务器触发器正在更新Microsoft SQL Server 2005 - 9.00.3042.00（X64）2007年2月10日00:59:02版权所有（c）1988-2005 Windows NT 5.2上的Microsoft Corporation Enterprise Edition（64位）（Build 3790： Service Pack 2）

我一直在想将服务器SP更新到SP4可能会解决问题吗？

有没有人有共鸣为什么这可能会使服务器变得更糟糕

修订

是的，我实际上硬编码了这些值并简化了它应该运行的SQL语句

DECLARE @MatterNumber as varchar(50)
SET @MatterNumber = (SELECT i.MAtternumber FRom Inserted as i) + '-1'
Print @MatterNumber

UPDATE [FSSQLPROD01].[collectionsDELETE].[dbo].[collections] 
       SET Loan_Number_1 = ‘123’
       WHERE file_number =  @MatterNumber

但是一旦我将一个声明的Varible值设置为Loan_Number_1或任何其他的columes，这就是问题开始发生的时候

DECLARE @LoanNumber as varchar(50)
SET @LoanNumber =    (SELECT i.Comments FRom Inserted as i)
    Print @LoanNumber
DECLARE @MatterNumber as varchar(50)
SET @MatterNumber = (SELECT i.MAtternumber FRom Inserted as i) + '-1'

Print @MatterNumber –-I print here I see 70003-1

UPDATE [FSSQLPROD01].[collectionsDELETE].[dbo].[collections] 
       SET Loan_Number_1 = @LoanNumber

       WHERE file_number =  @MatterNumber

Print @MatterNumber –-I print here I see 70003-1

触发器用于更新单个记录。当我们进行批量插入/更新时，它们不起作用。 因为SQL Server triggers runs only 1 time per UPDATE. 如果在单个语句中修改3000行，则触发器不会触发3000次。你的触发器只会触发一次。所以这就是它更新随机行的原因（尽管它应该是第1行）。
