Hello,
the details of my problem are described at
http://uwyn.com/greenenergy.txt
I basically have a set of tables with one product table and other tables
that contain labels and legends for each row in the product table. I'm
looking for a way to write one query that retrieves all the products and
the count of labels and legends, 0 should be returned if none are
present. The fact of doing several joins and aggregate functions
together returns undesired results.
Can anyone solve this query, or do I have to write a count query for
each linked table (one for labels and one for legends)?
Thanks a lot for the help,
Geert
