Question

在SQL Server中，您需要检查每个SQL语句的错误。例如，如果我在一个事务中有3个更新，我需要一些代码，如：

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;

此案例的其他任何解决方案都有更简单的代码吗？例如，像c＃style：

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

Answer 1

您可以像在c＃

中一样使用try catch语法

 BEGIN TRY
    -- ....
 END TRY
 BEGIN CATCH
    -- ....
 END CATCH

Begin Try
    SET NOCOUNT ON
    Set XACT_ABORT ON
    Begin Tran
        --Your Query
    Commit Tran
End Try

Begin Catch
    RollBack Tran
    Select ERROR_MESSAGE() as Msg, ERROR_NUMBER() as Num
End Catch
