Hi BASE coders, I can't seem to be able to count the number of distinct reporters on a particular array through the API, although it seems efficient enough with raw MySQL:
select count(distinct r.external_id) as count from Reporters r left join Features f on (r.id = f.reporter_id) left join ArrayDesignBlocks adb on (f.arraydesignblock_id=adb.id) left join ArrayDesigns ad on (adb.arraydesign_id = ad.id) where (ad.name = "Array name here"); +-------+ | count | +-------+ | 19805 | +-------+ 1 row in set (0.36 sec) I tried this, but there's no "group by" possible on a DataQuery (I'm getting and UnsupportedOperationException) DataQuery<FeatureData> featQuery = baseArray.getFeatures(); featQuery.include(Include.SHARED); featQuery.join(Hql.innerJoin("reporter", Item.REPORTER.getAlias())); featQuery.group(Hql.property(Item.REPORTER.getAlias(), "externalId")); count = featQuery.count(dc); I also tried going from the other direction (from Reporter.getQuery()), but you can't join to 'features' it seems. Am I missing something? (Obviously we have to treat Affy differently, but that's easy enough as getNumFeatures() is suitable.) many thanks, Bob. -- Bob MacCallum | VectorBase Developer | Kafatos/Christophides Groups | Division of Cell and Molecular Biology | Imperial College London | Phone +442075941945 | Email [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
