SELECT DATE_FORMAT( DATE_SUB( DATE_SUB(CURDATE(), INTERVAL WEEKDAY(CURDATE()) DAY), INTERVAL 1 WEEK), ‘%Y-%m-%d 00:00:00’) AS ‘上周一’;
SELECT DATE_FORMAT( SUBDATE(CURDATE(), WEEKDAY(CURDATE()) + 1), ‘%Y-%m-%d 23:59:59’) AS ‘上周末’;

SELECT DATE_FORMAT( SUBDATE(CURDATE(),DATE_FORMAT(CURDATE(),’%w’)-1), ‘%Y-%m-%d 00:00:00’) AS ‘本周一’;
SELECT DATE_FORMAT( SUBDATE(CURDATE(),DATE_FORMAT(CURDATE(),’%w’)-7), ‘%Y-%m-%d 23:59:59’) AS ‘本周末’;
