Find below a living example based on examples on this xwiki.org page... http://extensions.xwiki.org/xwiki/bin/view/Extension/Query+Module http://www.idisantiago.es/bin/XWQL/BlogEntriesByCategory http://www.idisantiago.es/bin/XWQL/BlogEntriesByCategory?viewer=code HTH!

I have several "Blog.BlogPostClass" objects and I try to make an HQL query in order to get BlogPosts which belong to a particular category. This is the category property of my objects : <property type="DBTreeList" name="category"> <link rel="self" href="http://192.168.11.34:8080/xwiki/rest/wikis/xwscomintech/spaces/Blog/pages/%20Tous%20vendeurs/objects/Blog.BlogPostClass/0/properties/category"/> <attribute value="category" name="name"/><attribute value="Category" name="prettyName"/> <attribute value="0" name="unmodifiable"/> <attribute value="0" name="disabled"/> <attribute value="1" name="relationalStorage"/> <attribute value="input" name="displayType"/> <attribute value="1" name="multiSelect"/> <attribute value="1" name="size"/> <attribute value=", " name="separator"/> <attribute value="0" name="cache"/> <attribute value="Blog.CategoryClass" name="classname"/> <attribute value="" name="customDisplay"/> <attribute value="doc.fullName" name="idField"/> <attribute value="4" name="number"/> <attribute value="doc.parent" name="parentField"/> <attribute value="1" name="picker"/> <attribute value="" name="separators"/> <attribute value="value" name="sort"/> <attribute value="" name="sql"/> <attribute value="" name="tooltip"/> <attribute value="" name="validationMessage"/> <attribute value="" name="validationRegExp"/> <attribute value="name" name="valueField"/> <attribute value="Blog.Categories,Blog.CategoryTemplate,Blog.News,Blog.Other,Blog.Personal" name="allowedValues"/> <value>Blog.Réunions thématiques</value></property> I would like to list BlogPosts in "Blog.Réunions thématiques" I tried this query : #set($hql = ", BaseObject as obj, DateProperty as prop1, StringProperty as prop2 where doc.fullName=obj.name and obj.className='Blog.BlogPostClass' and obj.id=prop1.id.id and obj.id=prop2.id.id and prop2.id.name='category' and prop2.value='Blog.Réunions thématiques' and prop1.id.name='publishDate' and prop1.value is not null and doc.space='Blog' order by prop1.value desc ") I saw that the type of my property was "DBTreeList" so I tried to replace StringProperty by DBStringListProperty but no success ... I need help please :-) Thanks _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users Nota: A información contida nesta mensaxe e os seus posibles documentos adxuntos é privada e confidencial e está dirixida únicamente ó seu destinatario/a.
