Filtering deleted pages seems not to work with SQLStore3 as well
Has this problem been solved in the meantime? The problem with deleted pages showing up as result also occurs with SMW 2.0 / MW 1.23.8
I'm not aware that this issue still persists in 2.0. If you can a provide a producible scenario and post it on [0] with reference to this thread (together with the versions used MW/SMW/+ other SMW related extensions). [1] is related to the SPARQLStore and was fixed in SMW 2.1.

Thank you very much for looking into my test wiki and for your analysis. Since I think the answer you sent me might be interesting for other people as well, I post an extract of your mail here:
MWJames mailed on 9 January 2015 at 18:18: Your ask query actually means "give me all pages in namespace Test" because Test: is registered as separate NS.
{{#ask: [[Test:+]]
| ?attribute1
| ?attribute2
}}
Since it is an unconditional query, it returns all possible pages even those deleted because the SQLStore doesn't delete a subject entry it sets it to be empty [0] leaving the subject (Page3/Page4) to remain in the smw_object_ids table. See also note [1], which states that "TODO: Possibly delete ID here (at least for non-properties/categories, if not used in any place in rels2)"
I added a simple condition to the query and got rid of the empty pages in the result:
{{#ask: [[Test:+]] [[attribute1::+]]
| ?attribute1
| ?attribute2
}}
MWJames, thank you very much for your fast reply and your analysis.
