If your table is not terribly big, you can
try something like
SELECT a.col1,a.col2, COUNT(*) as row_number
FROM yourTable a,yourTable b
WHERE a.col1 >= b.col1 -- I'm assuming col1 is primary key
GROUP BY a.col1,a.col2
ORDER BY row_number
This is pure SQL, should work in every version...

select row_number(), col1, col2...
FROM tableName
Thanks a lot!
