Jonathan, I think it would behoove you to read "How To Ask Questions The Smart Way". Pay particular attention to - Be Precise <http://catb.org/%7Eesr/faqs/smart-questions.html#beprecise> - and Don't Claim You Have Found A Bug<http://catb.org/%7Eesr/faqs/smart-questions.html#id306810> In this case, I believe you should post example table definitions, sample data, and the exact query which replicates the issue. Don't use your actual tables - create the smallest, simplest sample tables which still experience the issue. Your "bug" is likely in the GROUP BY. -- -jp Many people never stop to realize that a tree is a living thing, not that different from a tall, leafy dog that has roots and is very quiet. deepthoughtsbyjackhandy.com
