I'm using SA with SQLite, and after executing session.close() and

pass
mapper(A, a)
I want the default value of A.id2 to be that of a A.id. So, for
Hi all,
browsing the SQLAlchemy docs I coudn't find any references to a
particular SQLite feature, ON CONFLICT clause (http://www.sqlite.org/
lang_conflict.html), is there any support for this in SA? What I want
to do is this, create my database as such:
CREATE TABLE songs(

Greetings everyone,
does SQLAlchemy somehow support SQLites' ATTACH DATABASE statement? I
have a in-memory SQLite database that I want to dump to file, so I was
thinking of using ATTACH to do it. Any other ideas welcome ;).
Thanks in advance,
Karlo.

attach database ...wow i never knew it had that ! if its a matter of
issuing the string attach database, just use literal text() or
engine.execute().
Me neither ;), until the other day I started looking for an efficient
way to dump
