Roy Bøhmer	Sunday 07 August 2005 11:10:13 am Could someone give an example on how to use the group_by parameter when doing a content-list or content-tree fetch? I can't find anything in the docs on that, and some trial and error as resulted in only trial and errors :-) Thanks!
Roy Bøhmer	Sunday 07 August 2005 11:37:38 am I found this thread http://ez.no/community/forum/setup_design/group_by_parameter_in_fetch_function, but I still need some more hints. Can I group by a custom date/time attribute? How? It seems like it only picks the first node - more like a 'unique' kind of function. I would like it to return an array containing one array for each group. Enlight me, please :) - roy

Samuel Sauder	Monday 16 October 2006 7:43:28 am I was trying to figure this out too. Note that group_by is deprecated: http://ez.no/doc/ez_publish/technical_manual/3_8/reference/modules/content/fetch_functions/list <i>The optional "group_by" parameter (grouping on a date/time basis) is deprecated since this functionality is not supported by Oracle and PostgreSQL.</i> This doesn't make any sense to me... Is EZ saying that Oracle and PostgreSQL don't support GROUP BY syntax in SQL?
