ThinkPHP中关联查询(即多表联合查询)可以使用 table() 方法或和join方法,具体使用如下例所示: 1、原生查询示例: 代码如下: $Model = new Model(); $sql = 'select a.id,a.title,b.content from think_test1 as a, think_test2 as b where a.id=b.id '.$map.' order by a.id '.$sort.' limit '.$p->firstRow.','.$p->listRows; $voList = $Model->query($sql); 2、join()方法示例: 代码如下: $user = new Model('user'); $list = $user->join('RIGHT JOIN user_profile ON user_stats.id = user_profile.typeid' ); 3、table()方法示例: 代码如下: $list = $user->table('user_status stats, user_profile profile')->where('stats.id = profile.typeid')->field('stats.id as id, stats.display as display, profile.title as title,profile.content as content')->order('stats.id desc' )->select();
