How can i store and retrive image / sound files to and from Remaote sql server

[Askar]

Dear Friends,
Now i can store and retrieve sound and image files in local database. now i want to store and retrieve the same in remote sql server database.

I can store the binary data into remote sql by converting the byteArray to QString while using the insert command. while retrieving i could'nt get original format.
thanks,
Askar
