    <p>Here's and example of a script which creates an Indexed View Grouped By the Hour. I also have 2 others for Day and Month. The table UserPoints stores a record whenever points are awarded to the User with an exact DateTime timestamp called CreationDate.</p> <pre> CREATE VIEW [dbo].[HourlyPoints] WITH SCHEMABINDING AS SELECT [Count] = COUNT_BIG(*) --Required by SQL Server ,[UserId] ,[PointTypeId] ,[Points] = SUM(Points) ,[Hour] = DATEADD(hour, DATEDIFF(HOUR, 0, [CreationDate]), 0) FROM [dbo].[UserPoints] GROUP BY ProfileId ,PointTypeId ,DATEADD(hour, DATEDIFF(HOUR, 0, [CreationDate]), 0) GO CREATE UNIQUE CLUSTERED INDEX [IX_HourlyPoints_UserId_PointTypeId_Hour] ON [HourlyPoints] ([UserId],[PointTypeId],[Hour]) GO CREATE NONCLUSTERED INDEX [IX_HourlyPoints_PointTypeId_Points_Hour] ON [HourlyProfilePoints] ([PointTypeId],[Points],[Hour]) INCLUDE ([UserId]) GO </pre> <p>I'm trying to make sure I have the right indexes to query this Indexed View for a leaderboard which will rank Users based on the PointType &amp; Sum of Points.</p> <p>For example, my leaderboard query looks like this if I want a leaderboard based on the number points Users have earned with the last 3 hours. (or any other time window).</p> <pre><code>SELECT * FROM [HourlyPoints] WHERE [PointTypeId] = 1 --Gold Points AND [Hour] &gt;= '2013-06-13 01:00:00.000' AND [Hour] &lt; '2013-06-13 04:00:00.000' ORDER BY Points </code></pre> <p>What I'm worried about is that when I run that query I don't see the Execution Plan window showing that it is using the <strong>IX_HourlyPoints_PointTypeId_Points_Hour</strong> index. Shouldn't it?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
