Answer 1

根据计数对表格进行排序，然后使用LIMIT

SELECT * FROM

(SELECT count(*) rcount
    , DATE(create_date) crdate
    , fk_account_id accid
    , fk_caa_payment_pool_id poolId 
FROM  caa_payment_confirmation_hdr 
WHERE fk_caa_payment_pool_id IN 
(
    SELECT pk_caa_payment_pool_id 
    FROM caa_payment_pool 
    WHERE is_deleted = 0
) 
AND create_date >= '2017-08-01'
GROUP BY crdate
    , poolId
) A ORDER BY cnt DESC LIMIT 1
