Hi,
Do you know how to do this query with sqlalchemy?
*SELECT
Id, TIMEDIFF( End, Start)
FROM
plage
WHERE
TIMEDIFF(End,Start)=TIME('02:20:00');*
In my model, Start and End are DateTime
Start = Column('Start', DateTime)
End = Column('End', DateTime)

Try this:
from sqlalchemy import func

s = select( [Plage.Id,
func.timediff(Plage.Start, Plage.Start)
],
(func.timediff(Plage.Start, Plage.Start) = func.time('02:20:00'))
)
Thanks,

Thank you.
I will report the problem to the cx_Oracle list and see what they have to say.

Hi everyone!
I'm puzzled by a behaviour shown by SA 0.6.5 that 0.5.8 didn't show,
and I'm wondering what I'm doing wrong.. I have a simple uncascaded
many-to-many relationship, and if I try the following:
1) save a child
2) close the session
3) associate the child to a parent and save the parent

OK its actually a huge SQLA bug that an error isn't raised for that, which is

__table_args__ is expected to be a tuple or dict, so now an error
you've turned off save-update cascade so the c object is not placed into
the Session when you do the final save() of p.
Fix:
session.add_all(p.children)
p.children = []
save(session, p)

I'll also make the comment that while the pattern you're illustrating is very
unusual (cascade turned off, re-adding detached objects), the ORM is not being
consistent in its treatment of non-included child items in mutated
collections during flush, in that your append got flushed but the
hmm... but i was thinking of having specialized methods for every

you have a base class that would somehow specialize depending on the

No, SqlSoup only offers the base class for all objects as an option. Here's a
patch you can try:
diff -r 67d8f4e2fcb9
to get this working, i had to add a line to clear the cache entry for
attr if the base argument was passed in:
def entity(self, attr, schema=None, base=None):
if base: del self._cache[attr] # ADDED LINE
try:
t = self._cache[attr]
except KeyError, ke:
