请问这个查询如何转为thinkphp形式查询？

select count(*) from (select uid from oc_commission group by uid) as uid

回复内容：

select count(*) from (select uid from oc_commission group by uid) as uid

你的这个sql可以优化，一句搞定

select count(distinct(uid)) from oc_commission

tp:
M('Commission')->count(distinct(uid));

可以直接用原生代码查询

http://www.kancloud.cn/manual/thinkphp/1775 手册有子查询，你好好看看
$sql=M('oc_commission')->field('uid')->group('uid')->select(false);
$count=M('oc_commission')->table($sql.' a')->count()
如果报错，去github下载最新版本就不会报错了
