昨天：

SELECT DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 1 DAY), '%Y-%m-%d 00:00:00')
SELECT DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 1 DAY), '%Y-%m-%d 23:59:59')
           

上周：

SELECT DATE_FORMAT(DATE_SUB(DATE_SUB(CURDATE(),INTERVAL WEEKDAY(CURDATE()) DAY),INTERVAL 1 WEEK),'%Y-%m-%d 00:00:00')
SELECT DATE_FORMAT(SUBDATE(CURDATE(), WEEKDAY(CURDATE()) + 1), '%Y-%m-%d 23:59:59')
           

本周：

SELECT DATE_FORMAT( DATE_SUB(CURDATE(), INTERVAL WEEKDAY(CURDATE()) DAY), '%Y-%m-%d 00:00:00')
SELECT DATE_FORMAT( DATE_ADD(SUBDATE(CURDATE(), WEEKDAY(CURDATE())), INTERVAL 6 DAY), '%Y-%m-%d 23:59:59')
           

上月：

SELECT DATE_FORMAT( DATE_SUB(CURDATE(), INTERVAL 1 MONTH), '%Y-%m-01 00:00:00')
SELECT DATE_FORMAT( LAST_DAY(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)), '%Y-%m-%d 23:59:59')
           

本月：

SELECT DATE_FORMAT(CURDATE(), '%Y-%m-01 00:00:00')
SELECT DATE_FORMAT(LAST_DAY(CURDATE()), '%Y-%m-%d 23:59:59')
           

某个月有多少天：

SELECT DAY(LAST_DAY('2018-06-01'));

============================================================================================

今天

select * from 表名 where to_days(时间字段名) = to_days(now());      

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1      

近7天
