mysql 時間相關sql , 按天、月、季度、年等條件進行查詢

#今天
select *
from or_order_task where to_days(created_date)=to_days(now());

#近七天
select *
from or_order_task where date_sub(curdate(),interval 7 day )<=date(created_date);

#近七天
select *
from or_order_task where date_sub(curdate(),interval 30 day )<=date(created_date);

#本月
select *
from or_order_task
where date_format(created_date, '%Y%m') =  date_format(curdate(), '%Y%m');

#以月為緯度，取得上個月的數據 如當前時間為2018-07-02 則取數據范圍為所有數據中滿足字段名中月份為08-01至08-31的數據（可用於篩選下個月生日人員） 
#數據搜索范圍可通過最后判斷的值進行調整 0為當月 1是上個月 -1為下個月 以此類推
SELECT created_date FROM or_order_task WHERE PERIOD_DIFF(DATE_FORMAT(CURDATE(),'%m'),DATE_FORMAT(created_date,'%m'))= 1;

# 以年月為維度 取得下個月數據
SELECT *FROM or_order_task WHERE PERIOD_DIFF(DATE_FORMAT(CURDATE(),'%Y%m'),DATE_FORMAT(now(),'%Y%m'))=-1

#查詢本季度數據
select * from `ticket_order_detail` where QUARTER(use_time)=QUARTER(now());

#查詢上季度數據
select * from `ticket_order_detail` where QUARTER(use_time)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

#查詢本年數據
select * from `ticket_order_detail` where YEAR(use_time)=YEAR(NOW());

#查詢上年數據
select * from `ticket_order_detail` where year(use_time)=year(date_sub(now(),interval 1 year));
