Body
You will want to use a <code>PIVOT</code> function for this. If you have a known number of columns, then you can hard-code the values: <pre><code>select name, [Bronze], [Silver], [Gold], [Platinum], [AnotherOne] from ( select c.name, cr.description, r.typeid from customers c left join rewards r on c.id = r.customerid left join customerrewards cr on r.typeid = cr.typeid ) x pivot ( count(typeid) for description in ([Bronze], [Silver], [Gold], [Platinum], [AnotherOne]) ) p; </code></pre> See <a href="http://sqlfiddle.com/#!3/25d14/10">SQL Fiddle with Demo</a>. Now if you have an unknown number of columns, then you can use dynamic SQL to <code>PIVOT</code>: <pre><code>DECLARE @cols AS NVARCHAR(MAX), @query AS NVARCHAR(MAX) select @cols = STUFF((SELECT ',' + QUOTENAME(description) from customerrewards group by description, typeid order by typeid FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') set @query = 'SELECT name,' + @cols + ' from ( select c.name, cr.description, r.typeid from customers c left join rewards r on c.id = r.customerid left join customerrewards cr on r.typeid = cr.typeid ) x pivot ( count(typeid) for description in (' + @cols + ') ) p ' execute(@query) </code></pre> See <a href="http://sqlfiddle.com/#!3/25d14/9">SQL Fiddle With Demo</a> If you need to include the <code>Total</code> column, then you can use <code>ROLLUP</code> (<a href="http://sqlfiddle.com/#!3/25d14/14">Static Version Demo</a>): <pre><code>select name, sum([Bronze]) Bronze, sum([Silver]) Silver, sum([Gold]) Gold, sum([Platinum]) Platinum, sum([AnotherOne]) AnotherOne from ( select name, [Bronze], [Silver], [Gold], [Platinum], [AnotherOne] from ( select c.name, cr.description, r.typeid from customers c left join rewards r on c.id = r.customerid left join customerrewards cr on r.typeid = cr.typeid ) x pivot ( count(typeid) for description in ([Bronze], [Silver], [Gold], [Platinum], [AnotherOne]) ) p ) x group by name with rollup </code></pre> Dynamic version (<a href="http://sqlfiddle.com/#!3/25d14/17">Demo</a>): <pre><code>DECLARE @cols AS NVARCHAR(MAX), @colsRollup AS NVARCHAR(MAX), @query AS NVARCHAR(MAX) select @cols = STUFF((SELECT ',' + QUOTENAME(description) from customerrewards group by description, typeid order by typeid FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') select @colsRollup = STUFF((SELECT ', Sum(' + QUOTENAME(description) + ') as '+ QUOTENAME(description) from customerrewards group by description, typeid order by typeid FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') set @query = 'SELECT name, '+ @colsRollup + ' FROM ( SELECT name,' + @cols + ' from ( select c.name, cr.description, r.typeid from customers c left join rewards r on c.id = r.customerid left join customerrewards cr on r.typeid = cr.typeid ) x pivot ( count(typeid) for description in (' + @cols + ') ) p ) x1 GROUP BY name with ROLLUP' execute(@query) </code></pre>

Guidance

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.
