Dear Brenden 
we used this query on page type and pass it to the UniGrid on the Query attribute 
when loading the module interface it gives us an error 
Message: [SqlHelper.ValidatePagedQuery]: The paged query 'SaudiPedia.Article.GetOutdated' cannot be executed without the orderBy set.
the Query is 
select [ClassName], [ClassDisplayName], [DocumentModifiedWhen], [NodeID], [NodeSiteID], [DocumentCulture], [DocumentName], [DocumentNamePath] from view_cms_tree_joined inner join SaudiPedia_Article on ArticleID = DocumentForeignKeyValue and SaudiPedia_Article.ArticleUpdateNotificationDate <= GETDATE()
Where classname = 'SaudiPedia.Article' ORDER BY [DocumentName] ASC
