Re: Optimizer NOT using available indexes

Richard,

 Can a standard query or OPNQRYF use (not create) EVI's or is it SQL only?

The Vernon's suggestion of EVIs is a good one, it is as efficient with AND
as with OR: in most cases, if used, the optimizer derives bitmaps from EVIs
and cross them to find the RRNs of the selected records. Also, an EVI
gather more detailed statistics about the key values. You could also look
at the statistics thru iSeries Navigator.
