database - Mysql return count for last 7 days -


i having trouble run code below count rows grouped date returns wrong count each days

select date(date) days       ,coalesce(count(credits),0) credits  offer_process qa left join ( select date(now())-interval 30 day day_series              from(select 0                   union select 1  union select 2                   union select 3  union select 4                  union select 5  union select 6                 )            ) qb on date(date) = date(date)  date > date_sub(curdate(), interval 7 day)  group date(date)  order date(date) asc; 

insted of returning 1 each rows example, returns 7, not true

what one. return count of credits selected id each of last 7 days.

select (date(now()) - interval `day` day) `daydate`, count(`credits`) `credits` (     select 0 `day`     union select 1     union select 2     union select 3     union select 4     union select 5     union select 6 ) `week` left join `offer_process` on date(`date`) = (date(now()) - interval `day` day) , `id` = 50 group `daydate` order `daydate` asc
