date_add 函式用法

DATE_ADD （interval 1 day）

1.加一相當於小於21和等於21的資料查出來

 and date_format(w.CreateDate,'%Y-%m-%d %H:%i:%s')< date_format('2018-06-21','%Y-%m-%d %H:%i:%s')+1

2.不加一隻查詢小於21的資料查出來等於21的查不出來

 and date_format(w.CreateDate,'%Y-%m-%d %H:%i:%s')< date_format('2018-06-21','%Y-%m-%d %H:%i:%s')

3.相當於小於21和等於21的資料查出來， 與1.相同

-- and date_format(w.CreateDate,'%Y-%m-%d %H:%i:%s')< DATE_ADD(date_format('2018-06-21','%Y-%m-%d %H:%i:%s'),  interval 1 day)

4、小於等於是只查詢小於21的 =相當沒用

 and date_format(w.CreateDate,'%Y-%m-%d %H:%i:%s')<= date_format('2018-06-21','%Y-%m-%d %H:%i:%s')

5、可以在括號後面加一 與1.相同

 and date_format(w.CreateDate,'%Y-%m-%d %H:%i:%s')<= date_format('2018-06-21','%Y-%m-%d %H:%i:%s')+1
