Re: How to set the fid in different msid   
fids are unique across the entire database, so this isn't something  you should be trying to achieve.

Why?

Hi Dan!
     Thanks for your reply.Because I want to distinguish the media files of the different store types(USB or HardDrive).
 I need  select one of the store device ,and play the media files of the device selected.Further more ,In order to 
control the playback conveniently, I want to begin playing the fid with value=1 in differnt store types. thanks!
    Secondly,I want to view the playlist by album(artist),how should I do?
    please give me some advices,thanks very much!

RE: How to set the fid in different msid   
  If you inspect the library table columns, you will see that there are fields for all those attributes and more:

qdbc -dmme "select * from library limit 1"

 You can play from one storage type (select ... where msid=x), artist (select ... where artist_id=x), or many other 
attributes. You can find the artist_id values in the library_artists table (select * from library_artists) and the 
others work similarly.

Re: How to set the fid in different msid   
Tony's right.  You can filter the results from your query on the library 
table to limit your selection to a specific artist, mediastore, etc.

You shouldn't consider the fid to be the offset.  If you run the same 
query you should associate offset with the fid yourself.  You'll see the 
"row number" if you use the qdbc tool.

If you want to playback at a specific offset (ie, the Nth track in a 
track session) you can use mme_play_offset().

Re: How to set the fid in different msid   
Hi all!
     I known that all the media files fid is uniqe,they can not be changed.I have to query the library to get my result 
through limit.
    Now,I want to display the album art in the toutchscreen.
    Firstly,how can I associate the media file with the specified jpg? I located the media files in path of media/drive,
the album ipg on the path of media/artwork.
    Secondly,in order to display the album ipg,how can I get the metadata of the jig?
   thanks very much!
