I need to get name(of a collection) from Table1 and name of all the songs in that collection from table 3 . Table 2 is the connection between table 1 and table 3. music_playlist_id connects table 2 to table 1. tbl_content_common_id connects table 2 with table 3.

Table 1

CREATE TABLE IF NOT EXISTS `music_playlists` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `collection_id` int(10) NOT NULL,
  PRIMARY KEY (`id`)
)

Open in new window


Table 2

CREATE TABLE IF NOT EXISTS `playlist_song_mappings` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `music_playlist_id` int(11) NOT NULL,
  `tbl_content_common_id` int(11) NOT NULL,
  PRIMARY KEY (`id`)
)

Open in new window



Table 3

CREATE TABLE IF NOT EXISTS `tbl_content_commons` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `content_common_code` varchar(20) CHARACTER SET utf8 NOT NULL,
  `content_common_name` varchar(100) CHARACTER SET utf8 NOT NULL
)

Open in new window


Any help is much appreciated
