Re: Index Advisor Question

I'm curious as to why those who have offered alternatives would not take
the index advisor's advice.

Just looking to understand how a human expert discounts the advice of a
code-driven tool and hoping to gains some insight into how to use index
advisor better.

Why a 10 column index would be a red flag would be a good start - why is
that specifically bad ? (Wanting to understand why that is so, not question
the statement per se)

Hi Gary,

first of all, I would collect some data with database Monitor (STRDBMON)

to have a look to the real cost of those queries, then trying your
suggestion and have a look again to the cost in real life. If the cost (=
response time) is fine, best decision is: just do nothing.
