Hi all,
Currently i am having problem with this implementation. I have 4
tables, namely 1 parent table with 3 children tables.
Primary key from the parent table is assigned to each of the children
table. However, if primary key 1 is being assigned child table 1, it
cannot be re-assignment to
not sure if u are talking about inheritance patterns?

Hi,
I'm trying to use mx.TimeDelta instead of datetime.timedelta on an
Interval column (with Postgres).
It seems to work fine until I get to intervals a day, at which point
it fails with:
ProgrammingError: (ProgrammingError) invalid input syntax for type
interval: 1:00:00:00.00
'INSERT INTO
some_alg = sess.query(Alg).get(8)
sess.query(Email).filter(~Email.threads.any(Thread.alg==some_alg))
The clause Thread.alg=some alg *should* just generate the clause
thread.algid=8...it shouldn't pull in the alg table at all since
its not needed for many-to-one comparison.
That works
my understanding is that mx is no longer supported with psycopg2. You
might want to ask on their list; SA just passes through objects for
PG's date/time types.
