加入触发器？

Question

我正在尝试创建一个触发器，它将用收据信息更新历史记录表。

我的源表有一个SourceID和一个ReceiptID。

所以当我更新收据表时，我想将该记录复制到历史表，但我首先需要获取正在更新的源的SourceID。

这是我现在有：

ALTER TRIGGER [dbo].[trg_ReceiptHistory] 
ON [dbo].[tblReceipt] 
for UPDATE 
AS 
begin try 
INSERT INTO tblHistorySource(RecShipName, RecShipAddress, sourceID) 
select t1.shippingName, t1.shippingAddress, t2.sourceID 
from [DELETED] t1, tblSource t2 
where t2.receiptID = t1.receiptID 
end try 
begin catch 
SELECT 
ERROR_NUMBER() AS ErrorNumber, 
ERROR_SEVERITY() AS ErrorSeverity, 
ERROR_STATE() AS ErrorState, 
ERROR_PROCEDURE() AS ErrorProcedure, 
ERROR_LINE() AS ErrorLine, 
ERROR_MESSAGE() AS ErrorMessage; 
RAISERROR('Error in Source Hisotry Trigger' ,16,1) 
ROLLBACK TRAN 
END CATCH 

当我尝试做一个简单的更新到tblReceipt，我得到以下错误：

Msg 50000, Level 16, State 1, Procedure trg_ReceiptHistory, Line 24 
Error in Source Hisotry Trigger 
Msg 3609, Level 16, State 1, Line 1 
The transaction ended in the trigger. The batch has been aborted. 

我是不是做错了？请帮助:(

首先要做的是去掉CATCH，看到错误，我们可以从那里。

ALTER TRIGGER [dbo].[trg_ReceiptHistory] 
ON [dbo].[tblReceipt] 
for UPDATE 
AS 
--begin try 
INSERT INTO tblHistorySource(RecShipName, RecShipAddress, sourceID) 
select t1.shippingName, t1.shippingAddress, t2.sourceID 
from [DELETED] t1, tblSource t2 
where t2.receiptID = t1.receiptID 
/*end try 
begin catch 
SELECT 
ERROR_NUMBER() AS ErrorNumber, 
ERROR_SEVERITY() AS ErrorSeverity, 
ERROR_STATE() AS ErrorState, 
ERROR_PROCEDURE() AS ErrorProcedure, 
ERROR_LINE() AS ErrorLine, 
ERROR_MESSAGE() AS ErrorMessage; 
RAISERROR('Error in Source Hisotry Trigger' ,16,1) 
ROLLBACK TRAN 
END CATCH*/
