Question

This is the master table structure:

CREATE TABLE IF NOT EXISTS `gf_film` (

  `film_id` bigint(20) NOT NULL AUTO_INCREMENT,
  `user_id` int(20) NOT NULL,
  `film_name` varchar(100) DEFAULT NULL,
  `film_cat` varchar(30) CHARACTER SET latin1 DEFAULT NULL,
  `film_plot` longtext,
  `film_release_date` date DEFAULT NULL,
  `film_post_date` date DEFAULT NULL,
  `film_type` enum('Movie','Tv') CHARACTER SET latin1 DEFAULT 'Movie',
  `film_feature` enum('Y','N') CHARACTER SET latin1 NOT NULL DEFAULT 'N',
  `film_status` enum('ACTIVE','INACTIVE') CHARACTER SET latin1 NOT NULL DEFAULT 'ACTIVE',
  `film_modify` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `film_link_value` varchar(200) NOT NULL,
  `film_post_link` varchar(255) NOT NULL,

  PRIMARY KEY (`film_id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=21435 ;

This the child table through which I map between the above gf_film table and lowest gf_actor table:

CREATE TABLE IF NOT EXISTS `gf_film_actor` (

  `film_id` int(20) NOT NULL,
  `actor_id` int(20) NOT NULL,

  KEY `film_id` (`film_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

This another table from which I have to retrieve the actor name:

CREATE TABLE IF NOT EXISTS `gf_actor` (

  `actor_id` bigint(20) NOT NULL AUTO_INCREMENT,
  `actor_name` varchar(100) DEFAULT NULL,
  `actor_desc` longtext CHARACTER SET latin1,

  PRIMARY KEY (`actor_id`),
  UNIQUE KEY `actor_name` (`actor_name`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=60963 ;

And this the schema for gf_film_poster:

CREATE TABLE IF NOT EXISTS `gf_film_poster` (

  `film_id` int(20) NOT NULL,
  `website_poster_url` varchar(255) DEFAULT NULL,
  `original_poster_url` varchar(255) DEFAULT NULL,
  `default_poster_url` varchar(255) DEFAULT 'noposter.gif',

  UNIQUE KEY `film_id` (`film_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

After executing this query:

SELECT gf_film.film_id                                 ,
       film_name                                       ,
       DATE_FORMAT(film_release_date,'%d') AS DATE     ,
       DATE_FORMAT(film_release_date,'%m') AS month_ori,
       DATE_FORMAT(film_release_date,'%M') AS MONTH    ,
       DATE_FORMAT(film_release_date,'%Y') AS YEAR     ,
       film_release_date                               ,
       film_feature                                    ,
       film_modify                                     ,
       film_post_link                                  ,
       website_poster_url
FROM   gf_film
       LEFT JOIN gf_film_poster
       ON     gf_film.film_id=gf_film_poster.film_id

I am getting these results from database:

film_id,film_name,date,month_ori,month,year,film_release_date,
 film_feature,film_modify,film_post_link,website_poster_url

I need another column which contain the actors name and actor_id in one row related to each movies by joing the above query with gf_actor and gf_film_actor.
