When this query runs, SQL Server does an Index Seek and since the index points to the actual data pages, the Estimated Subtree Cost is only 0.0044572.This is by far the fastest access method for this type of query.Once the reference point has been established, the Price Index value of every other city in the database is calculated by comparing their cost of living to the cost of living in Prague.Therefore, if a city has a Price Index of 134, that means that living there is 34% more expensive than living in Prague. Once the reference point has been established, the Price Index value of every other city in the database is calculated by comparing their cost of living to the cost of living in Prague.Another thing you can see from these examples is ability to use non-clustered covering indexes where the index satisfies the entire result set.This is also faster then having to go to the data pages of the Heap or Clustered Index.Naturally, the more data entered, the more accurate the index and the calculations will be.

Each of these queries was run with no index as well as with a clustered and non-clustered indexes.This is the cost to SQL Server to execute the query.
