mysql查询返回错误＃1054

Question

我收到此错误，我不知道该怎么做

#1054 - Unknown column 'ple.playlists' in 'on clause'

请帮助，我正在phpMyAdmin直接测试，这是我的查询：

SELECT
  u.`idu` AS `user_id`,
  u.`username` AS `user_name`,
  u.`first_name` AS `first_name`,
  u.`last_name` AS `last_name`,
  u.`country` AS `user_country`,
  u.`image` AS `user_image`,
  u.`cover` AS `user_cover`,
  u.`description` AS `user_description`,
  pl.`id` AS `playlist_id`,
  pl.`name` AS `playlist_name`,
  t.`id` AS `track_id`,
  t.`title` AS `track_title`,
  t.`name` AS `track_name`,
  t.`art` AS `track_art`,
  t.`likes` AS `track_likes`,
  t.`downloads` AS `track_downloads`,
  t.`views` AS `track_plays`
FROM users AS u
INNER JOIN playlists AS pl
  ON u.idu=pl.by
INNER JOIN playlistentries AS ple
  ON pl.id=ple.playlists
INNER JOIN tracks AS t
  ON ple.track=t.id
ORDER BY `user_id` ASC, `playlist_id` ASC, `track_id` ASC
