ThinkPHP中关联查询实例_PHP
本文实例讲述了ThinkPHP中关联查询的用法。分享给大家供大家参考。具体分析如下:
在THINKPHP中关联查询(多表查询)可以使用 table() 方法或和join方法,如下示例所示:
1、table()
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();
2、join()
代码如下:
$user = new Model('user');
$list = $user->join('RIGHT JOIN user_profile ON user_stats.id = user_profile.typeid' )->select();
3、原生查询
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);
4、多表查询
代码如下:
$Model->field('user.name,role.title')->table('think_user user,think_role role')->limit(10)->select();
或:
代码如下:
$Model->field('user.name,role.title')->table(array('think_user'=>'user','think_role'=>'role'))->limit(10)->select();
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
