thinkphp 关联查询问题有两个表,一个是医院r_hospital,另一个是科室r_department。怎样关联查询,选择完医院之后,科室只显示该医院的科室,而不显示其他医院的了 thinkphp 关联查询 分享到: ------解决方案--------------------THINKPHP 中关联查询(多表查询)可以使用 table() 方法或和join方法,请看示例: 1、table() $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(); 2、join() $user = new Model('user'); $list = $user->join('RIGHT JOIN user_profile ON user_stats.id = user_profile.typeid' ); 3、原生查询 $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);
