Analyzing queries using Database Engine Tuning Advisor

There are few different ways that can help you in providing workload to DTA. One of the popular ways is to ask DTA about the query you are designing at the moment for performance point of view, so that DTA can analyze the query and provide suggestions, if any.

Getting ready

We will need two tables to demonstrate this recipe. Here is the script to create the same:

USE AdventureWorks2012
GO
IF OBJECT_ID('ProductDemo') IS NOT NULL
DROP TABLE ProductDemo
GO
IF OBJECT_ID('ProductModelDemo') IS NOT NULL
DROP TABLE ProductModelDemo
GO
select * into ProductModelDemo from Production.ProductModel
select * into ProductDemo from Production.Product
GO

We have just created two tables, named ProductDemo and ProductModelDemo, which don't have any index or statistics right now.

How to do it...

Now here is the query we want to execute and tune if possible:

SELECT
P.ProductID
,P.ProductModelID
FROM
ProductDemo AS P
JOIN
ProductModelDemo AS PM
ON
P.ProductModelID...
