MySQL查詢中的未知列ID

Question

有人可以幫助我我有2個MySQL查詢，當我嘗試運行它們時會得到未知的列ID。我想補充一點，我從2005年的SQLServer將這個數據庫MySQL和他們在SQL Server 2005中

這裏是他們的1運行良好：

SELECT DISTINCT g.id AS `genre` 
    FROM media_playlist_sequence MPS 
    INNER JOIN media    M ON M.`key`   = MPS.media_key 
    INNER JOIN media_playlists  MP ON MP.`key`   = MPS.playlist_key 
    INNER JOIN node_media_playlist NMP ON NMP.playlist_key = MP.`key` 
    INNER JOIN nodes    N ON N.`key`   = NMP.node_key 
    INNER JOIN media_files   MF ON MF.media_key  = M.`key` 
    INNER JOIN media_locations  ML ON ML.media_file_key = MF.media_file_key 
     AND ML.node_key = n.`key` 
    INNER JOIN media_genres  MG ON MG.media_key  = M.`key` 
    INNER JOIN genres    G ON G.`key`   = MG.genre_key 
WHERE M.is_ready = 1  
    AND MP.id = 'Channels'  
    AND N.id = 'VIC-WIN7' 
    AND mf.is_quad_image = 0

我的猜測是，這是一個區分大小寫的問題。 MySQL可以默認區分大小寫，而SQL Server不區分大小寫。
