// 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( 'user1 a, user2 b' )->where( 'a.id = b.id' ) ->field( 'name,sex' )->order( 'id desc' )->select(); |
帅的无语!
