If I have an integer column I can easily select the column minus one:
session.query(mytable.column - 1)
If I want to select a datetime column minus one minute, there doesn't
seem to be an easy way to do it.
I would have expected to be to do something like:
session.query(mytable.column -
seconds' AS
ano...

I'm using such an old version)

I've added a few extra columns to one of my tables (nothing fancy,
just plain Integers and Floats) and created them manually in the db.
Now every time I try to query an object from this table I get the
error in the subject. Using declarative in SA 0.6.3 on PG8.4.
Traceback below, any help is much
Hi, just wondering if there's support for window functions, or if
there's any plans to add this yet?
Thanks

Hi,
I have a query object to which I'm performing the following join and
filter:
Q = Q.outerjoin(Table.history_loader)
Q = Q.filter(TableHistory.tick == 123)
Table.history_loader is a dynamic loader that maps the two tables
based on their id property.
This produces the following
Silly mistake, this works fine now, thanks!

Hi
I'm using a few association proxies in a 1:1 relationship, it works
nicely, I have a proxy on table1 pointing to an attribute on table2,
and another on table1 that points to a relation between table2 and
table3. So what I really have is also a 1:1:1 relationship. Is there a
way to make a proxy
I actually just realised that it's not a 1:1:1 relationship, 1:1 and
many:1 in the case of table1:table2 and table2:table3 respectively,
but I don't think it really matters here, given I've already got
proxies that work!
