Now, The following query will get alternating even records from the above table "Information" −
mysql> Select id,Name from information group by id having mod(id,2) = 0; +----+---------+ | id | Name | +----+---------+ | 2 | Ram | | 4 | Aarav | | 6 | Krishan | +----+---------+ 3 rows in set (0.00 sec)
