至少你应该给出相关的表结构

跟框架有什么关系呢

你设计相关的数据库,相应的搜索数据即可

你可以贴出用户表和好友表的结构

大概语句,,,假设需要useraccount ,,

SQL code
SELECT f.*, u.useraccount FROM usersfriend AS f LEFT JOIN [user表名] AS u ON f.frienduserid=u.useridWHERE f.userid=[要找的用户id]<br><font color="#e78608">------解决方案--------------------</font><br>tp的联合查询不会,我用tp也是直接 query(sql语句)<br><font color="#e78608">------解决方案--------------------</font><br>基本SQL:<br>select usersfriend.*<br>  from usersfriend, userinformation<br>  where usersfriend.frienduserid = userinformation.userid<br><br><font color="#e78608">------解决方案--------------------</font><br>路过,积点分<div class="clear">
                 
              
              
        
            </div>
