假设我有以下表格结构:

t1
-------------
id // row id
userID_follower // this user is a follows another member
userID_following  // other member that this user 

是否可以运行单个查询来组合以下两个:

1. 这个人关注了多少用户

   从t1 WHERE userID_follower =".$ myID"中选择COUNT(id).".

2. 有多少用户关注此人

   从t1 WHERE userID_following =".$ myID"中选择COUNT(id).

谢谢.
