Hello,
I have used the following to query my data:
#----start
class th(object):
pass
mapper(th,th_table)
a=session.query(th).filter(sqlalchemy.and_(th.APPLIED_TEST==1,th.CODING_DATE=='20080325')).all()
#end
I noticed that there is a query
th.query().filter(sqlalchemy.and_(th.APPLIED_TEST==1,th.CODING_DATE=='20080325')).all()
but it gives me a :
AttributeError: 'generator' object has no attribute 'all'
What is the difference between these queries? Both of them are ORM
based since they used mapped python class?!?
Which one should be used? And why I wouldn't use one of them?
