Re: changing indexes

Hi

There is nothing wrong in doing this, but it sounds like you are possibly
trying to reinvent what analysis services does!!!

If you are inserting a significant number of records your indexes may be
fragmented and therefore defragmenting them or re-creating them are
necessary activities. You may wish to change the fillfactor if your tables
are read only and have a lower fill factor whilst loading and 100% fill
factor when readonly.

You may also want to consider moving this data load offline into a separate
database, then you swap in the new data when it has been built and reduce
downtime. The whole database could be read only!
