Question

我有：

enum('Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun')<BR>

我希望能够从今天开始排序＆＃39;或日期（date_format（％a））

有没有办法解决枚举的索引和ROL的种类？（抱歉，那里有老派汇编语言）或者，首先在PHP中更容易吗？目前我只是有一个常规的

SORT BY students.day (the enum field)

Answer 1

你可以在SQL中这样做：

select * from sortday
order by 
   (myday + DAYOFWEEK(NOW())) MOD 7;

mysql> select * from sortday;

| id | myday | val            |
