ThinkPHP多表联合查询的常用方法_PHP

ThinkPHP

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：

$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：

$user = new Model('user');
$list = $user->join('RIGHT JOIN user_profile ON user_stats.id = user_profile.typeid' );

3、table()方法示例：

$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();
