SQL error

HI everyone,


I´m trying to capture all the possible errors that a statement can have. And, if there´s any error i will do a rollback; What i´m trying to do its:
BEGIN
  insert into temp values(1, 2, 3);
  IF ANY_ERROR_OCCURED THEN
     ROLLBACK;
     RETURN FALSE;
  END IF;
END;

Did anyone knows how can i do that?

Thanks a lot!
