Leandro, do you really believe that couple of thin paragraphs is enough to rebuff insightful and quite substantial original message?

To add to UDT problems (which were posted sometime ago in the c.d.t exchange with Paul Brown, so I plot only summary here):

1. Creating User Defined indexes is hard.
2. User Defined statistics is expert users domain.
3. UDT optimization is virtually non-existent.
Even though 1-3 might be not fundamental problems, they create unsatisfactory Return-On-Investment when creating a UDT of only limited utility requires unproportional effort. Received on Fri Aug 27 2004 - 19:03:34 CEST
