Catch error in insert select

I want to perform select insert. If error on inserting or update, it should roll back and return "Error message" if not it should return "Successful". Is this correct? I am not sure how to do this.


begin transaction

insert into table_1
(date, name, username)
select date, name, username
from table_2

update table ...etc

if @@error <> 0
begin
    if @@trancount > 0
        rollback
    return
end

BEGIN TRY

   -- do your stuff here

   -- If code execution makes it here, good to go.
   COMMIT TRAN tr
END TRY

BEGIN CATCH
   -- If code execution makes it here then an error occured.   Rollback everything that happened up to the BEGIN TRANS.
   ROLLBACK TRAN tr
END CATCH

Hi Jim,

Can it be returned with a message? If errors, it return "my error message", if no error, it should return " my message".

Sure, right before the ROLLBACK, something like...

SELECT 'An error occured' + ERROR_PROCEDURE() as message, 
   ERROR_NUMBER() as number, 
   ERROR_MESSAGE() as message

Open in new window
