Hello,
I'm using the declarative extension and was wondering (after searching
the docs) how to elegantly delete multiple objects at once, preferably
without loading them in first. Suppose you've got a mapped class like
this:
class Person(Base):
__tablename__ = 'persons'
stamp =
query has both bulk delete and update methods
http://www.sqlalchemy.org/docs/05/reference/orm/query.html#the-query-object
count = session.query(Person).filter(... whatever criteria
...).delete(synchronize_session=False)

bindparams in said clause. Is there a way to do this?

Hello,
I need to query, insert, update and delete from already existing

After much trial and error, nothing worked. Then I came across this

the func. call is a SQL expression which can't be bound to a bind
parameter. that has to stay in the values() clause. e.g.
