Re: [sqlalchemy] In-memory sqlite database to blob?
you can ATTACH the memory database to a file and then transfer tables using insert-from-select.Don't think there's a way to go straight to a stream, though.

Is this possible? It is possible but potentially difficult. You could accomplish this by using the backup facility (sqlite3_backup_*) to push the in-memory database to the remote location, perhaps over a network-mounted file share. (http://www.sqlite.org/backup.html) It would likely be easier to use iterdump in pysqlite to generate a database dump and push the SQL dump text to a server. If you are trying to avoid hitting the disk, perhaps you can create the sqlite db on an in-memory filesystem. Then you could use normal filesystem operations to manipulate the resultant database. In any case, SQLAlchemy won't be directly helpful here. Cheers, M -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

Re: [sqlalchemy] In-memory sqlite database to blob?
Thanks for the pointers. I'l probably just write it to a file initially to keep it simple!
