保持存储过程运行即使有错误

Question

我有一个存储过程需要运行即使有一些错误。所以这里有一个小例子

CREATE PROCEDURE FirstProcedure
@SomeParams 

AS BEGIN


Declare Db_Cursor Cursor For
Select * From #TmpR
Open Db_Cursor
Fetch Next From Db_cursor Into 
@SomaValues
While @@Fetch_Status = 0 
    Begin
    set @ERR = 0 
    exec [SecondProcedure] @SomaValues
    set @ERR = @@ERROR

    if @ERR <> 0 begin
       -- do some things in case of error 
     end
    Fetch Next From Db_Cursor Into 
@SomaValues

    End

END

如果第二个程序 returns 出现错误，我将它捕获到 @ERR 变量并做一些其他事情，但我希望光标移动到运行直到 [=19= 结束]，因为如果不能使用 SecondProcedure 插入 100.000 中的 2-3 行不是很重要？

我能做什么？

使用Try/Catch

CREATE PROCEDURE FirstProcedure
@SomeParams 

AS BEGIN


Declare Db_Cursor Cursor For
Select * From #TmpR
Open Db_Cursor
Fetch Next From Db_cursor Into 
@SomaValues
While @@Fetch_Status = 0 
  Begin
    begin try
       exec [SecondProcedure] @SomaValues
    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;
    end catch

    Fetch Next From Db_Cursor Into @SomaValues
  End
  close db_cursor
  deallocate db_cursor

END
