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()
$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\' )->select();
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);
4、多表查询
$Model->field(\'user.name,role.title\')->table(\'think_user user,think_role role\')->limit(10)->select();
或:
$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。
