Hi,
The following session is never saved to the db, not even a schema is
created, but a query returns correctly. I assume that there is local
caching going on. but session.dirty etc doesn't show anything. So, two
questions:
First, how (if possible) can I force sqla to hit the db? In this case, how
can I force it to return an error for the line
print session.execute(q1).fetchall()
?
Second, how can I get sqla to show there is data unsaved to the db? I
tried dirty and new. Thanks in advance.
Regards, Faheem
