if you ~have~ a program, i.e. application code written in some language like php, then the best place to append the row numbers is right there in your application language as you loop over the returned rows
doing it with SQL is a ~lot~ more complicated and inefficient

ya its ok...
but major prob is that, i want to show that records on a web pager, the records may exceed more than 1 page...
so its hard to maintian a counter on diff pages...
and i dont want to pas that counter argument in addressbar....

- on the 1st page, your query would have LIMIT 0,20 for the first 20 rows
- on the 2nd page, your query would have LIMIT 20,20 for the second 20 rows
- on the 3rd page, your query would have LIMIT 40,20 for the third 20 rows
- and so on
no row numbers required
