Hello Guys,
This might seem like a bit of a naive question but I'm looking for your
advice. Being from the UK we operate on Daylight Savings Time which gives us
a one hour offset on times for a few months of the year.
I currently have a DateTime column which is declared like so:

I was just wondering if the folowing possible.
A record has severall groups connected through a N:M relation.
But it also has a parent. What I would like is that all the groups

record.
When the parent has a group added or
Hi Werner,
IIUC func.now is a database function.
Ah, ok, that makes fair sense.
You should be able to use datetime instead i.e.:
created = Column(DateTime, default=datetime.datetime.utcnow)
modified = Column(DateTime, default=datetime.datetime.utcnow,
onupdate=datetime.datetime.utcnow)
this is sort of inheritance of data, right?
the best i've made so far about this is to get (somehow) all the Rs
each with it's groups, and then do the inheritance (union over the
path towards root in your case) over the result rows by hand. if u
find a better way let me know...

so I modified a code to use hotshot module, basically I added

below. I played with code a little bit and it seems to me that most

is there a way to query on running averages in sqlalchemy?
Eg for a baseball database how could I query on

Thanks for any clues.
