Join Martin Guidry for an in-depth discussion in this video Using indexes, part of SQL Server 2012: Designing Database Solutions.
- In this section, I'd like to talk about using Indexes…in SQL Server 2012 to help improve the performance…of certain types of queries.…I have a query staged that we're going to work with…in your Exercise Files.…I'll take all of this and copy it into a new query window.…Let's talk a little bit about what this query does.…First line, Line 1, will drop the clean buffers…And what that does is it clears out the cache.…
All of the data that may have been cached in memory…will be cleared out.…We commonly do this when we're running…some performance tests,…'cause we want to make sure every query…runs in the same environment,…so we clear out the cache before each query.…The query starts on Line 5, we'll see that…we're going to select the top 200 CarrierTrackingNumbers.…We're selecting from the SalesOrderDetail table.…Line 7 shows us that we're looking…where CarrierTrackingNumber IS NOT NULL,…Line 8 shows us that we are going to ORDER the results…BY CarrierTrackingNumber,…so I'll go ahead and execute this query.…
All right, we see that our query completed.…
