* use a MySQL database of your choice, and import the script netjuke.sql from
issue 18039
(http://www.openoffice.org/issues/showattachment.cgi?attach_id=8345&file=netjuke.sql)
* create a ODBC data source for this database, and a OOo data source using the
ODBC data source
* create a new query, use the select statement in netjuke_query.sql from issue
18039
(http://www.openoffice.org/issues/showattachment.cgi?attach_id=8346&file=netjuke_query.sql)
* display this query in the data source browser
=> another query is executed. It seems that OOo incorrectly changed the
statement from

  SELECT `artists`.name, `albums`.name
  FROM `albums`, `tracks`, `artists`
  WHERE `albums`.id = `tracks`.al_id AND `artists`.id = `tracks`.ar_id
  GROUP BY `tracks`.al_id
  ORDER BY `artists`.name

to

  SELECT `artists`.`name`, `albums`.`name`
  FROM `albums`, `tracks`, `artists`
  GROUP BY `tracks`.`al_id`
  HAVING  0 = 1

which definately isn't equivalent
