即使存在错误，也要保持存储过程运行

Question

我有一个即使存在一些错误也需要运行的存储过程。所以这里一个小exameple

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 

如果第二个过程的回报和错误我抓住它的@ERR变量，做一些其他的事情，但我想光标运行，直到表的末端，因为它不是非常重要，如果从100.000的2-3行不能使用SecondProcedure插入？

我该怎么办？

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 

如果你希望有可能成为第二个存储过程的错误
