left join 等连接查询遇到同名字段覆盖问题

可以在查询时给字段赋别名，但是需要注意以下：*的位置要在最前面，放在其他地方都会出错。这种写法同名覆盖的字段还在，然后在*的后面加上别名字段，已经可以满足所有需求了

SELECT *,r.id as rid,u.id as uid FROM remarks_tblogs as r left join user_tblogs as u on r.userId=u.id ORDER BY r.id desc

P.S.  一段thinkphp数据库查询代码，注意各种别名的使用

$remarks = M('remarks_tblogs');$remarkInfo = $remarks->table('remarks_tblogs as r')    ->field('*,r.id as rid,u.id as uid')    ->join('left join user_tblogs as u on r.userId=u.id')    ->order('r.id desc')->select();
