This page is something of a hack so those
|
|
easily scared off by funky solutions, don't
|
|
touch it! :P
|
|
|
|
There is a central problem to this page, it's
|
|
impossible to order before grouping in SQL, and
|
|
it's slow to run sub queries, so we had to get
|
|
creative for this one.
|
|
|
|
The solution I settled on abuses the way
|
|
$DB->to_array() works. What we've done, is
|
|
backwards ordering. The results returned by the
|
|
query have the best one for each GroupID last,
|
|
and while to_array traverses the results, it
|
|
overwrites the keys and leaves us with only the
|
|
desired result. This does mean however, that
|
|
the SQL has to be done in a somewhat backwards
|
|
fashion.
|
|
|
|
Thats all you get for a disclaimer, just
|
|
remember, this page isn't for the faint of
|
|
heart. -A9
