    <p>I have never tried to pass a variable value into a subquery before, and I seem to be going about it wrong. I am not receiving any errors, but I also get no results, whereas if I hard-code the values for startdate, enddate &amp; role into the subquery, it runs correctly. </p> <p>================edit =======================</p> <p>My bad, I posted the earlier test script I was playing with which was indeed full of errors, sorry for that. Here is the actual code I am working with, in full:</p> <pre><code>DECLARE @Role varchar, @StartDate datetime, @Enddate datetime; SET @Role = 'Volunteer'; SET @StartDate = DATEADD(d, -100, getdate()); SET @Enddate = getdate(); SELECT rolename, Category, [1] as [1 Day],[2] as [2 Days],[3] as [3 Days],[4] as [4 Days],[5] as [5 Days],[6] as [6 Days],[7] as [7 Days] FROM (SELECT CriminalHistoryID, vps.RoleName, 'Rec2PreClr' as Category, DATEDIFF(d, chc.ReceiveDate, chc.PreClrDate) as DaysDif FROM dbo.v_PersonStatus vps INNER JOIN dbo.CriminalHistoryCheck chc ON vps.PersonID = chc.PersonID WHERE chc.ReceiveDate BETWEEN @StartDate AND @Enddate AND vps.rolename = @Role and DATEDIFF(d, chc.ReceiveDate, chc.PreClrDate) BETWEEN 0 and 7 UNION SELECT CriminalHistoryID, vps.RoleName, 'PreClr2Clr' as Category, DATEDIFF(d, chc.PreClrDate, chc.FinalDate) as DaysDif FROM dbo.v_PersonStatus vps INNER JOIN dbo.CriminalHistoryCheck chc ON vps.PersonID = chc.PersonID WHERE chc.ReceiveDate BETWEEN @StartDate AND @Enddate AND vps.rolename = @Role AND DATEDIFF(d, chc.PreClrDate, chc.FinalDate) BETWEEN 0 and 7 UNION SELECT CriminalHistoryID, vps.RoleName, 'Rec2Clr' as Category, DATEDIFF(d, chc.ReceiveDate, FinalDate) as DaysDif FROM dbo.v_PersonStatus vps INNER JOIN dbo.CriminalHistoryCheck chc ON vps.PersonID = chc.PersonID WHERE chc.ReceiveDate BETWEEN @StartDate AND @Enddate AND vps.rolename = @Role AND DATEDIFF(d, chc.ReceiveDate, FinalDate) BETWEEN 0 and 7 ) UNIONqry PIVOT (count(CriminalHistoryID) for DaysDif in ([1],[2],[3],[4],[5],[6],[7])) pvt Order by RoleName, Category </code></pre> <p>The values for @Startdate, @Enddate &amp; @Role do not seem to be getting into the subquery. Do I need to do something to tell the sub to look outside the box?</p>

    1. COWhat error are you getting? Are you sure you are running *all* the code at the same time? You can't run the `declare` and then run the subquery -- the definitions only last while for the statement that is running.

    2. COIt looks like this isn't all of the code - there's a UNION there. If you ran all of this as written here, it would fail with a syntax error.

    3. COIf you don't set @VolStatus, it will be NULL. Depending on your ANSI_NULL setting, you may or may not get data... I'm guessing this might be your problem though.

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.
