获取当前日期：select curdate()

获取当前日期前一天：select  date_sub(curdate(),interval 1 day)

获取当前日期后一天：select date_sub(curdate(),interval -1 day)

日期时间格式化：DATE_FORMAT(date_sub(NOW(),interval 1 day),"%Y-%m-%d %H:%i:%S")

举几个date_sub()的例子：

date_sub("2016-08-01",interval 1 day) 表示 2016-07-31

date_sub("2016-08-01",interval 0 day) 表示 2016-08-01

date_sub("2016-08-01",interval -1 day) 表示 2016-08-02

date_sub(curdate(),interval 1 day) 表示 2016-07-31

date_sub(curdate(),interval -1 day) 2016-08-02

date_sub(curdate(),interval 1 month) 表示 2016-07-01

date_sub(curdate(),interval -1 month) 表示 2016-09-01

date_sub(curdate(),interval 1 year) 表示 2015-08-01

date_sub(curdate(),interval -1 year) 表示 2017-08-01

查询一天前的数据

SELECT * FROM `TD_FRAMEWORK_Event_Notify` WHERE create_time <=DATE_FORMAT(date_sub(NOW(),interval 1 day),"%Y-%m-%d %H:%i:%S");
