数据库查询c＃where子句

Question

我有一个这样的数据库：

我需要在列中选择最高值。目前我正在使用此查询，但它无法正常工作：

string qry = @"select hawkername, address, postal, xcoord, ycoord, popularity from uploadphoto where MAX(popularity) "; 

有人可以指导我吗？

按人气排序并限制为1

select hawkername, address, postal, xcoord, ycoord, popularity 
from uploadphoto 
order by popularity DESC
LIMIT 1;
