in recent SQLA versions the classes can be fed right into select(): stmt = select([MyClass]).where(MyClass.foo == "bar") however, you can just as easily use Query and just get Query.statement to get a core statement as well. If you Query against individual columns too, e.g. sess.query(MyClass.id, MyClass.bar), there's little performance difference between that and Core in updated versions (see the performance suite and run some experiments with it: http://docs.sqlalchemy.org/en/rel_1_0/orm/examples.html#module-examples.performance > Happy hacking. > Krishnakant. > -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
