I have one :memory: database open and I want to make a copy of it into another :memory: database. When I open the 2nd :memory: database and call attach on the first one specifying ':memory:' as the file name, it allows me to do this. However when I loop through the tables copying them into the 2nd one, it is still empty after this has been done. I think the first :memory: database might be attaching to, uh, itself.
Is there a way to specify the name of a memory database uniquely? Something like ':memory:2'? Nothing that I've tried works. -Dave Gierok -----Original Message----- From: Dan Kennedy [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 07, 2007 9:56 AM To: sqlite-users@sqlite.org Subject: Re: [sqlite] ATTACH and :memory: databases On Wed, 2007-02-07 at 09:37 -0800, Dave Gierok wrote: > I would like to attach a :memory: database to another :memory: database.

Use ':memory:' as the filename.
