No!

I have to do this "strange" and "long" statement also a view thousand
times ... so I always have to create the temp table again and again and
if I index the table it costs me more time. 

As far I am relativly new to SQL, I ask you:
Where's the difference between and indexed temp (!!!) table and an
unindexed one? The main table is of course fully indexed ;-)

Cheers, Markus
