Maybe I should back up and make sure I understand what it is you want. What you have written is a left outer join, but what you described was a right outer join.
If you want the records in query B which do not exist in query A, then you need to flip flop, Query B needs to be in your FROM clause and Query A needs to be in the value list stuff. Here is a simple example I just tried that seems to work fine for me. <cfquery datasource="your_datasource" name="queryA"> SELECT 11 AS ID1, 21 AS ID2, 31 AS ID3, 'exists in both' as description UNION SELECT 12, 22, 32, 'exists in both' UNION SELECT 13, 23, 33, 'exists only in A' UNION SELECT 14, 24, 34, 'exists only in A' </cfquery> <cfquery datasource="your_datasource" name="queryB"> SELECT 11 AS ID1, 21 AS ID2, 31 AS ID3, 'exists in both' as description UNION SELECT 12, 22, 32, 'exists in both' UNION SELECT 15, 25, 35, 'exists only in B' UNION SELECT 16, 26, 36, 'exists only in B' </cfquery> <cfquery dbtype="query" name="qry_left_outer"> SELECT * FROM queryB WHERE NOT (queryB.ID1 in (#valuelist(queryA.id1)#) and queryB.ID2 in (#valuelist(queryA.id2)#) and queryB.ID3 in (#valuelist(queryA.id3)#)) </cfquery> <cfdump var="#qry_left_outer#"> ~Brad -----Original Message----- From: Richard White [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 01, 2008 2:13 PM To: CF-Talk Subject: Re: left outer join on query of query function Hi Brad, i thought that would work but not producing the result as expected, it still returns no rows on 2 queries where i know queryb has 15 rows that are not in querya therefore it should be returning those 15 but is not thanks ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:308412 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
