As you know SQLAlchemy has to call setinputsizes. This is an event hook
that let's you change what it will do. You use event.listen along with
your create_engine call and that's it. The rest of that program is just an
example.

Thanks for adding this feature!
Since I don't know SQLAlchemy that good yet, can you explain exactly what's
going on?
Do I have to do all the Base related lines? What do they do?
If I add this event for an engine in one file/class, does it affect that
engine when passed around to other
the feature at https://gerrit.sqlalchemy.org/#/c/zzzeek/sqlalchemy/+/795/
will be part of SQLAlchemy 1.2.9 and will allow the following program
to work:
from sqlalchemy import *
from sqlalchemy.orm import *
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import event
Adding to Mike's response...
I think you're using two sessions...
you select this:
user = Users.query.filter_by(username='foo').first()
and save this
db.session.add(user)
when you select, i think that's using some flask-sqlalchemy syntactic sugar
to select the session. a 'raw'
I apologize for my inpatient tone in my previous email. I would hope that
everyone in this mailing list feels welcome.

this is a very simple issue to debug with basic programming
techniques, first off, put echo='debug' in your create_engine so you
can see all SQL and results:
e = create_engine("postgresql://scott:tiger@localhost/test", echo='debug')
next, if you are running over to a SQL command line vs.

Ok. I ran the script 10 times on a clean table.
Now I run raw sql:
SELECT *
FROM test_user
WHERE (last_receive_time + INTERVAL '1 second' * timeout) < NOW();
The result: 10 records.
Now I run script one more time. Still 0 records using from_statement.
amount records using NOW() = 0
