Hello,

[sql2005]
Do you know which feature of SQL gives an output like this:
"Missing Index Details from ExecutionPlan1.sqlplan. The Query Processor
estimates that implementing the following index could improve the query cost
by 24.8260%. "


TIA

Can you explain what you mean by "which feature of SQL"?
Also, where are you seeing these messages?

As of SQL 2005, the optimizer can see if there are any indexes it feel
could have helped for the query it optimizes. The information you can
see in the missing indexes DMV's and also in the XML showplan. SSMS
2008 even show this in the graphical representation of the XML
showplan.

Tibor,

A list of such suggestions were in the document submitted by an external
consultant. I have never seen this and was curious as to how I can reproduce
the same.

How can I get to XML showplan in SQL2008?
