如何爲SQL Server中的T-SQL中的事務捕獲錯誤？

Question

在SQL Server中，您需要檢查每個SQL語句的錯誤。例如，如果我有一個交易3次更新，我需要一些這樣的代碼：

declare @HasError int 
begin tran 
Update tab1 set .... 
Set @HasError = @@error; 
Update tab2 set ... 
Set @HasError = @@error; 
Update tab3 set ... 
Set @HasError = @@error; 

If @HasError<>0 
    rollback tran; 
else 
commit tran; 

這種情況更簡單的代碼，任何其他解決辦法？例如，類似於C＃風格：

begin tran 
    try 
    { 
     Update tab1 set ....  
     Update tab2 set ... 
     Update tab3 set ... 
     commit tran; 
    }catch(error){ 
     rollback tran; 
    }

    Select ERROR_MESSAGE() as Msg, ERROR_NUMBER() as Num 
End Catch

您可以使用一個嘗試捕捉語法在C＃
