Hi,
Thanks Ragnar. This, and an other GROUP BY + name query within output got me
there.
<cfquery name="get_news" datasource="#ds#">
SELECT DISTINCT news_id, news_header, segment, segment_id, count(*)
FROM news_table
NATURAL JOIN segments_table
NATURAL JOIN read_history
WHERE account_id = #Url.account_id#
GROUP BY news_id, news_header, segment, segment_id ORDER BY count DESC
</cfquery>
...
<cfoutput query="get_news" group="news_id">
<cfquery name="get_seg" datasource="#ds#">
SELECT segment_name
FROM segments_table
WHERE segment_id = #segment#
</cfquery>
#news_header# - #get_seg.segment_name# - #count#
</cfoutput>
