Jeff,

IIRC, this will sometimes happen with a DDS defined file because an SQL index has more statistical
information that the query engine can use.

But you say your file is a DDL defined table....so I don't know....

Is the suggested index the exact primary key? How many fields in the PK?

Subject: Index advisor advising index on primary key

At our LUG meeting earlier this week a fellow midranger (Thanks Rob!)
gave a presentation on things you might not have known about on the i.
One of them was iNav index advisor, which I did not know about.

I cleaned out the advice since much of it was old so it would start fresh.

On our item master file, it is advising that I create an index on field
ITNBR. This file is an SQL table created via DDL (not DDS) and ITNBR is
the primary key. Does this advice make sense? Why would it advise an
index on the primary key?

Thanks.
