SqlAlchemy Quickie: How to use Distinct

May 15, 2009 § Leave a comment

distinct() method is accessible from Query object. The documentation is kind of obscure, so hopefully this post is helpful for others.

Example:

 @classmethod
def get_all_category(cls):
return meta.Session.query(cls.category).distinct().all()

Reference:
