The first one: *db(*(db.asset.tipo=='SC') & (db.asset.is_active==True)*)*
Returns a Set (this is not a python set but a pyDAL one) The second one: (db.asset.tipo=='SC') & (db.asset.is_active==True) Actually returns a Query A set is what you get when you call your DAL instance with a query as argument. The Grid is actually expecting a query because it can do more than one call to the DAL with that same query to get different things.
