Hi, I'm trying to get the values of two fields from xwikiattahment table with this HQL query: select att.filename,att.date from xwiki.xwikiattachment att, xwiki.xwikidoc doc where doc.fullName='Event.IIXornadaIDIS' and att.filename like '%abstract%' and att.date > '2012-03-01' and att.docId=doc.id order by att.filename; The query fails. When used to get only one field, it works fine. For instance... select att.date from xwiki.xwikiattachment att, xwiki.xwikidoc doc where doc.fullName='Event.IIXornadaIDIS' and att.filename like '%abstract%' and att.date > '2012-03-01' and att.docId=doc.id order by att.filename; or select att.filename from xwiki.xwikiattachment att, xwiki.xwikidoc doc where doc.fullName='Event.IIXornadaIDIS' and att.filename like '%abstract%' and att.date > '2012-03-01' and att.docId=doc.id order by att.filename; and, the SQL equivalent to the in troubles query works also fine. This way... select att.XWA_FILENAME,att.XWA_DATE from xwiki.xwikiattachment att, xwiki.xwikidoc doc where doc.XWD_FULLNAME='Event.IIXornadaIDIS' and att.XWA_FILENAME like '%abstract%' and att.XWA_DATE > '2012-03-01' and att.XWA_DOC_ID=doc.XWD_ID order by att.XWA_FILENAME; Please, where am I wrong when trying select att.filename,att.date from xwiki.xwikiattachment att,...? I'm running XWiki Enterprise 2.4.30451. Thanks for your help!
