          教你如何写thinkphp多表查询语句 (2011-04-07 13:18:44)转载▼
         1、table()函数
         thinkphp中提供了一个table()函数，具体用法参考以下语句：
         $list=$Demo->table('think_blog blog,think_type type')->where('blog.typeid=type.id')->field('blog.id as id,blog.title,blog.content,type.typename as type')->order('blog.id desc' )->limit(5)->select();
         echo $Demo->getLastSql(); //打印一下SQL语句，查看一下
          
         2、join()函数
         看一下代码：
         $Demo = M('artist');
         $Demo->join('RIGHT JOIN think_work ON think_artist.id = think_work.artist_id' );
         //可以使用INNER JOIN 或者 LEFT JOIN 这里一定要注意表名的前缀！
         echo $Demo->getLastSql(); //打印一下SQL语句，查看一下
         */

     } else {
