This code works when executed within a if __name__ == '__main__'
block in the .py that contains the model:
s = MySession(bind=e)
q = s.query(DatabaseTable).filter(DatabaseTable.TABLE_CAT=='credit')
for i in q:
print i
However, if I take it out and put it in a separate file, I get an
error like this. I hope that this is something simple that I am doing
wrong?
