Question

I am working in SSRS 3.0 with a SQL table including the following fields:

ApptID    BookedBy   ConfirmedBy   CancelledBy

I also have a parameter setup to select which users to filter by (matches data in the BookedBy, ConfirmedBy and CancelledBy columns) called @Scheduler (which is a multi vale parameter/array).

I need to get a count for booked, confirmed and scheduled for how many times any value in the Scheduler parameter shows up in that column.

Basically:

COUNT(BookedBy IN (@Scheduler)) AS BookedCount

Can anyone help me out with the syntax for doing this?

Answer 1

Try this

 SELECT Count(BookedBy = @Scheduler) as [BookedCount],
        Count(ConfirmedBy = @Scheduler) as [ConfirmedCount],
        Count(CancelledBy = @Scheduler) as [CancelledCount]
 FROM tablename
 WHERE BookedBy = @Scheduler OR 
       ConfirmedBy = @Scheduler OR
       CancelledBy = @Scheduler

NB – Not tested might contain typos

If your input is a list separated by commas you can convert that to a table. See a reference like this:

http://www.projectdmx.com/tsql/sqlarrays.aspx

For this use case I’d recommend one of the solutions that saves the result in a CTE (since you only need to convert your input once and this will be fastest)

Then you could use that table (called sTable with column name) like this:

 SELECT Count(Bo.Name) as [BookedCount],
        Count(Co.Name) as [ConfirmedCount],
        Count(Ca.Name) as [CancelledCount]
 FROM tablename
 LEFT JOIN sTable Bo ON BookedBy = Bo.name
 LEFT JOIN sTable Co ON ConfirmedBy = Co.name 
 LEFT JOIN sTable Ca ON CancelledBy = Ca.name

I guess this will work but it does not seem as nice as the others:

 SELECT (SELECT COUNT(*) FROM table WHERE BookedBy in (@Scheduler)) AS [BookedCount],
        (SELECT COUNT(*) FROM table WHERE ConfirmedBy in (@Scheduler)) as [ConfirmedCount],
        (SELECT COUNT(*) FROM table WHERE CancelledBy in (@Scheduler)) as [CancelledCount]
