Just to make sure, did you refresh your data after moving to SqlStore3? You need to do that before any data will show up.

Hi,

in a wiki which runs
MediaWiki 1.19.1
PHP 5.4.4 (apache2handler)
MySQL 5.5.0-m2-log
Semantic MediaWiki (Version 1.8)
SMW Store 2

I get a list of the pages in category Maps when I use the query:
{{#ask: [[Category:Maps]]}}

and format=debug shows as SQL somethin like
SELECT DISTINCT t2.smw_title AS t,t2.smw_namespace AS ns FROM `smw_ids` AS
t2 INNER JOIN `smw_inst2` AS t0 ON t2.smw_id=t0.s_id WHERE
(t0.o_id='1597134') ORDER BY t2.smw_sortkey ASC LIMIT 51 OFFSET 0;

however, when I use the same data in a wiki which runs
MediaWiki 1.20.0
PHP 5.4.4 (apache2handler)
MySQL 5.5.0-m2-log
Semantic MediaWiki (Version 1.9 alpha) (c61b465)
SMW Store 3

I get no result with the same query and format=debug shows: Empty result,
no SQL query created.

However looking in Special:Categories I see in both wikis the same number
of pages.

Is this a bug, a changed behaviour or just temporarily not supported? Or
is it a local problem with Store 3?
Is there maybe any alternative syntax for the #ask query which would
simulate the old behaviour?

Thanks
Guenther
