关于时间的查询，比如本月，本年，本季度

-- mysql查询本季度
-- 今天
select * from ticket_order_detail where to_days(use_time) = to_days(now());
-- 7天
SELECT *FROM ticket_order_detail  where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date( use_time)
-- 近30天
SELECT *FROM ticket_order_detail  where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date( use_time)
-- 本月
SELECT *FROM ticket_order_detail  WHERE DATE_FORMAT(  use_time, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )
-- 上一月
SELECT *FROM ticket_order_detail  WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format(  use_time, '%Y%m' ) ) =1
#查询本季度数据
select * from `ticket_order_detail` where QUARTER(use_time)=QUARTER(now());
#查询上季度数据
select * from `ticket_order_detail` where QUARTER(use_time)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));
#查询本年数据
select * from `ticket_order_detail` where YEAR(use_time)=YEAR(NOW());
#查询上年数据
select * from `ticket_order_detail` where year(use_time)=year(date_sub(now(),interval 1 year));
