bitsCN.com 简单来说就是在查询中使用count以及更多字段

select count(id),id,name from table 

很尴尬的,我的环境是5.5的,这个是能获取到结果的,但是运行到服务器就不行了
好吧,报了一个错误

#1140 - Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if there is no GROUP BY clause  

在5.x是可以用的,不过其它字段的值只是获取到第一条的信息,好吧,我承认这是一个偏门的写法,无实际意义,可能是新手的一个语法结构思路不清晰所致。
好吧,作为一个新人,我还是明智的使用WAMP的版本切换功能切换过去吧bitsCN.com
