mysql - 显示由日期条件给定的列的所有日期列表

Question

我对 Stackoverflow 中的问题有疑问

我认为我的问题之前太复杂了，

因此，我创建了一个新问题:

WHERE DATE(e.created_at) BETWEEN DATE('2016-11-13') AND DATE('2016-11-15')

我需要这样的格式，

+-----------+----+----+----+----------------
   another  | 13 | 14 | 15 | another again
+-----------+----+----+----+----------------

Answer 1

试试这个

 SELECT ....,
    IF(DATE((e.created_at)= str_to_date("2016-11-13","%Y-%m-%d"),1,0) as '13',
    IF(DATE((e.created_at)= str_to_date("2016-11-14","%Y-%m-%d"),1,0) as '14',
    IF(DATE((e.created_at)= str_to_date("2016-11-15","%Y-%m-%d"),1,0) as '15',
    ......
