As far as I know to select last 7 rows from MySQL table in backward order, it needs to be done:
SELECT * FROM `table`
ORDER BY id DESC
LIMIT 7;
But I want to select penult 7 rows. After that I want to select 7 rows, except 14 last rows, etc...
Thereby, I wonder what sql query it should be to select 7 rows, except last N * 7 rows?
