I am/was doing this in application, with 2.8.15 . I simply attached the on-disk database to the memory, and then wrote a bunch of dump queries to drop the memory data to disk (from the memory db connection):
ATTACH 'C:\my_database_on_disk.sqlitedb' AS diskdb ; Unfortunately, I don't think you can execute transactions on the attached database in 2.8.15, and I couldn't think of a way to attach to the memory database from the disk database. I think you can execute transactions on the attached db in 3.x, though. It works ok, although since I was using the in-memory database as a preliminary db (multithreaded app), my dump queries got ugly, and quite slow on large sets, because I had to do the checks to ensure that the in-memory db wasn't dumping data that already existed in the database (I know, triggers, etc., but I hadn't tried those yet, and INSERT OR IGNORE scares me). I eventually substituted writing text sql scripts to disk, and then executing those directly into the disk database, which saved me 25-30% of the insert time. --Keith On Fri, 18 Feb 2005 04:01:32 +0100, chorlya <[EMAIL PROTECTED]> wrote: > I gues you could attach in-memory db to a newly created disk db and > then do something like > > CREATE TABLE newDiskTbl AS SELECT * FROM memoryTbl > > Take a look at http://www.sqlite.org/lang_createtable.html for more details > > Regards, > chorlya > > On Fri, 18 Feb 2005 11:13:40 +1100, [EMAIL PROTECTED] > <[EMAIL PROTECTED]> wrote: > > > > I have a situation where I start with an in-memory DB, then need to save the > > entire thing to a new disk DB.
