Fournier Hi,
Fournier So I assume in this case the only way to have distinct results is to use
Fournier GROUP BY topic clause ?
If you do this, you can't still use 'ORDER BY date' as 'date' is not
part of the GROUP BY

a.. The optimiser may handle DISTINCT differently if you are using
'hidden' columns in a join or not.

Hi Jocelyn,
I wonder how works DISTINCT when using it with the following join.
Ex :
mysql SELECT DISTINCT topic FROM
searchmainhardwarefr7,searchjoinhardwarefr7 WHERE
searchmainhardwarefr7.numreponse=searchjoinhardwarefr7.numreponse AND
(mot='test') AND date = '2002-03-24' ORDER BY date

Hi Jocelyn,
I don't have a quick/sure answer for you, but am wondering about the
relationship

In fact what it's odd is when I use EXPLAIN, I don't see anywhere DISTINCT
in the EXPLAIN result :
That's because the MySQL optimizer converts your distinct into a group by.

Well done Carsten!
Which may bring us back to the relationships between the data/columns
being used to control the query.
Jocelyn: Did you try out my previous suggestions?
Please advise,
