如何查找SQL Server执行存储过程时尝试捕获的异常类型

Question

I am executing a stored procedure which has some code inside it and I put it inside a try catch block like

BEGIN Transaction Tran1  
BEGIN Try
    //Stored procedure code
COMMIT TRANSACTION  Tran1   
END Try

BEGIN Catch
ROLLBACK TRANSACTION Tran1 
    raiserror('Cannot commit transaction', 16, 1, @@error);
    return;
END Catch

When any error occurred it goes to the Catch block and raises the error which is a user defined error but it does not raise what type of error actually occurred. So how could I get what type of error that really occurred as we do in C# while executing it from front end like

Try  
{  
  //Some code  
}  
Catch(Exception ex)  
{  
  MessageBox.Show(ex.message);  
}

Please provide me solution for this

Answer 1

The error raised is catchable as a SqlException

eg

catch (SqlException sqlEx)
{
   if (sqlEx.Number == 50000)
   {
      // 
   }
}

You can use the msg_id flavour of RAISERROR to customize the Number in SQL, or better still, use THROW

Answer 2

You can try

BEGIN Transaction Tran1  
BEGIN Try
   //Stored procedure code
COMMIT TRANSACTION  Tran1   
END Try

BEGIN Catch
ROLLBACK TRANSACTION Tran1      
   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
