Hi David,

One quick one. In session II of Stairway to SQL Server Indexes you mentioned that:

* Non Clustered Index Is a sorted set of entries.

I have little doubt on it.

If we run below query you will find that the output of first query on "CONTACTS_INDEX" table with "FULLNAME" index on "LastName, FirstName" the out put is not sorted.

SELECT * FROM DBO.CONTACTS_INDEX WHERE LASTNAME LIKE 'Ste%'

But when we run the below query on "CONTACT_NOINDEX" table results are sorted.

SELECT * FROM DBO.CONTACTS_NOINDEX WHERE LASTNAME LIKE 'Ste%'

So now my question is why is it so? If I do a select on Heap table I am getting data sorted but when I do a select on table with NonCluster index data is not sorted.
