我有下面的mysql查询,但是执行大约需要5分钟,如何减少执行时间
select
revenue_center_group.description as rc_group,
revenue_center.description as revenue_center,
count(ytd.members) as total_ytd_members,
count(lytd.members) as total_lytd_members
from revenue_center
left join revenue_center_group on revenue_center_group.id = revenue_center.revenue_center_group_id
left join (
select membership.id as members,
membership.rc_id as rc_id
from membership
where membership.status =1
and DATE(membership.join_date)>= (SELECT DATE_FORMAT((SELECT DATE_FORMAT(date(now()) - INTERVAL 1 MONTH, '%Y-%m-%d')) ,'%Y-01-01 00:00:00'))
and DATE(membership.join_date)<= (SELECT DATE_FORMAT(LAST_DAY(date(now()) - INTERVAL 1 MONTH), '%Y-%m-%d 23:59:59'))ytd on revenue_center.id = ytd.rc_id
left join (
select
membership.id as members,
membership.rc_id as rc_id
from membership
where membership.status =1
and DATE(membership.join_date)>= (SELECT DATE_FORMAT((SELECT DATE_FORMAT((SELECT DATE_FORMAT(date(now()) - INTERVAL 1 MONTH, '%Y-%m-%d'))
- INTERVAL 1 YEAR, '%Y-%m-%d')) ,'%Y-01-01 00:00:00'))
and DATE(membership.join_date)<= (SELECT DATE_FORMAT((select DATE_FORMAT(LAST_DAY(date(now()) - INTERVAL 1 MONTH), '%Y-%m-%d')
- INTERVAL 1 YEAR),'%Y-%m-%d 23:59:59'))lytd on revenue_center.id = lytd.rc_id
group by revenue_center_group.description,revenue_center.description with rollup;
