    <p>I'm trying to count Holiday bookings (B.ID) for dates 2 days either side of today.</p> <p>It works but my results are separated as I have to introduce the end date of the holiday too, which varies for each start date (holidays have different durations).</p> <p>The separates out my counts. What I need is one count for each date. Is there a way of working round this? I kinda just want to exclude the vwReturnDate from the group by but have to put it there as I've used it in my count.</p> <p>In English I want - For each [date] count the number of [B.id] where [B.Depart] &lt;= [date] and [vwReturnDate] > [date]</p> <p><img src="https://i.stack.imgur.com/eUvqv.png" alt="enter image description here"></p> <pre><code>DECLARE @startDate DATE DECLARE @endDate DATE SET @startDate = Getdate()-2 SET @endDate = Getdate()+2; WITH dates(Date) AS ( SELECT @startdate as Date UNION ALL SELECT DATEADD(d,1,[Date]) FROM dates WHERE DATE &lt; @enddate ) SELECT [Date] as 'Calendar Date', --CONVERT(VARCHAR(10), [Date],103) AS 'Date' -- ,CONVERT(CHAR(2), [Date], 113) AS 'Day' -- ,CONVERT(CHAR(4), [Date], 100) AS 'Month' -- ,CONVERT(CHAR(4), [Date], 120) AS 'Year', Case when B.Depart &lt;= [date] AND vwR.ReturnDate &gt;=[date] then count (B.ID) end AS 'Number of holidays live on date' FROM [dates] left join Booking B on B.depart=[Date] inner join Quote Q on Q.ID=B.QuoteID inner join vwReturnDate vwR on vwR.ID=B.ID Group by [date], B.depart, vwR.ReturnDate order by [date] OPTION (MAXRECURSION 0) GO </code></pre>

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.
