One solution is to retain the last ID from the previous scan:
SELECT *
FROM Users
WHERE session_key IS NOT NULL
AND id > your_last_id
LIMIT 300;
will this ensure that no row is repeated when i itereate over the table? what are the rows ordered by?
thanks
Ya, sorry I forgot to include the order by.
SELECT *
FROM Users
WHERE session_key IS NOT NULL
AND id > your_last_id
ORDER BY id
LIMIT 300;
Yes there will not be any repeated rows sence you are using a order set that who's ID are greated than the last set.
