So is it true that this cannot currently be done with sqlalchemy? I have
been reading the docs, but no clues yet.

Hi,
I have an object (with references) I get from a session on database A
and I want to copy it (deep copy) to database B. I tried expunging it
from the first session and adding it to the second. What's the best
practice to do this?
thanks!

Hi MikeCo,
I tried your example, and got this error from SA 0.5.

ults.
A, B exit.
Re-run B.
B finds 1 row where FOO=NULL and sets FOO=B.
B exits.
Does that help clarify?
thank you.

Thank you,
So I changed my query to a select/for update. then re-added the updated
rows in the transaction, then committed.

Hi,
I have 2 records in the database. I made an expression to update only
1 record, but all are getting updated.

Hi,
Thanks for the response. I'm still fairly new to SA but am very
impressed with this package!
I tried a variety of combinations of mappings. If I use just the
parent_id,parent it would seem to make sense logically if my children
only have one parent.
The tables generate fine. But when I try
13 matches
