yes, it's in the latest 0.3.6 version... this sometime it's hopeful :-) - orm: - the full featureset of the SelectResults extension has been merged into a new set of methods available off of Query. These methods all provide "generative" behavior, whereby the Query is copied and a new one returned with additional criterion added. The new methods include: filter() - applies select criterion to the query filter_by() - applies "by"-style criterion to the query avg() - return the avg() function on the given column join() - join to a property (or across a list of properties) outerjoin() - like join() but uses LEFT OUTER JOIN limit()/offset() - apply LIMIT/OFFSET range-based access which applies limit/offset: session.query(Foo)[3:5] distinct() - apply DISTINCT list() - evaluate the criterion and return results no incompatible changes have been made to Query's API and no methods have been deprecated. Existing methods like select(), select_by(), get(), get_by() all execute the query at once and return results like they always did. join_to()/join_via() are still there although the generative join()/outerjoin() methods are easier to use. -- +------------------------------------------------------------+ Glauco Uri - Programmatore glauco(at)allevatori.com Sfera Carta Software® [EMAIL PROTECTED] Via Bazzanese,69 Casalecchio di Reno(BO) - Tel. 051591054 +------------------------------------------------------------+ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
