Есть 4 MYSQL запроса, приведу пример двух, думаю по аналогии сделаю и с 4мя.
SELECT COUNT( `id` ) AS `lll` FROM `link_base` WHERE `create_date` = CURDATE()
SELECT COUNT( `id` ) AS `aaa` FROM `ad_base` WHERE `create_date` = CURDATE()
SELECT
(SELECT COUNT( `id` ) FROM `link_base` WHERE `create_date` = CURDATE()) AS `lll`
(SELECT COUNT( `id` ) FROM `ad_base` WHERE `create_date` = CURDATE()) AS `aaa`
