mysql的in选择结果过，按照in里面的排序排序

因为如果不用下面的order by field(列名字，数字)，则结果是按照id的自然干顺序排的

只有加了下面的ｏｒｄｅｒ　ｂｙ　后才是按照ｉｎ里面的顺序排序！

select user.us_fansno as '号',sub.usb_score as '积分' 

from b_user user,b_usersub sub 

where user.us_id = sub.us_id 

and user.us_fansno in (

  28296 ,

  1802568 ,

  1167907 ,

  331085 ,

  32336 ,

  608608 ,

  2036032 ,

  875829 ,

  2098730 ,

  1988862

)
order by field(
