How to pass parameter count from report to SQL query

I need some help on how to pass the count of the number of parameter values selected for a report in to the SQL query.

My query is as follows:
SELECT        ActiveCrew.[Resource No_], Crewtbl_1.[Global Dimension 2 Code], Crewtbl_1.Team
FROM            (SELECT        No_ AS [Resource No_]
                          FROM            dbo.[Gallowglass Live$Resource]
                          WHERE        ([Global Dimension 2 Code] IN (@Region)) AND (Team IN (@Team)) AND (Blocked = 0) AND (Type = 0) AND (No_ <> 'ZZZ') AND (No_ <> 'CC1') AND 
                                                    (No_ <> 'CC2') AND (No_ <> 'CC3') AND (No_ <> 'CC4') AND (No_ <> 'CC5') AND (No_ <> 'CC6') AND (No_ <> 'CC7') AND (No_ <> 'CC8')) 
                         AS ActiveCrew INNER JOIN
                             (SELECT        TOP (100) PERCENT No_, [Global Dimension 2 Code], Team
                               FROM            dbo.[Gallowglass Live$Resource] AS [Gallowglass Live$Resource_1]
                               ORDER BY [Global Dimension 2 Code], Team, No_) AS Crewtbl_1 ON ActiveCrew.[Resource No_] = Crewtbl_1.No_
WHERE        (NOT EXISTS
                             (SELECT        No_
                               FROM            (SELECT        No_
                                                         FROM            dbo.[Gallowglass Live$Gallowglass Resource Skill]
                                                         WHERE        (Type <> 4) AND ([Skill Code] IN (@Skills))
                                                         GROUP BY No_
                                                         HAVING         (COUNT(*) = 2)) AS d
                               WHERE        (ActiveCrew.[Resource No_] = No_)))
ORDER BY ActiveCrew.[Resource No_]

Open in new window


I can display the number of skills selected with teh Skills parameter using =Parameters!Skills.Count.

I need to get that value in to the part of the query that is COUNT(*) = 2

Theoretically it would be:

COUNT(*) = Parameters!Skills.Count

This doesn't work. Is there a way of doing this and if so how.

Thanks very much for any pointers you can give.

depends on the language your are using to issue the sql-call.
If the sql-query is assigned as a text-value  you can build it by concatenating the parameter with the text

instead of
xxx.sqltext = 'select .. from where count(*) = 2 order by 1'
make it
xxx.sqltext = 'select .. from where count(*) = ' & Parameters!Skills.Count & 'order by 1'

(or whatever the concatenation looks like in your language)

Thanks for the advice. I'm a bit of a novice so bear with me if I am not doing something obvious.

I am using SQL Business Intelligence Development Studio 2005 to design the report.

Here is what I am working with
User generated image

When I run the query I get this error:
An error occurred during local report processing.
An error has occurred during report processing.
Cannot read teh next data row for the data set Live_data.
Conversion failed when converting the varchar value ' & CInt(Parameters!Skills.Count) & ' to data type int.

I got this error both with and without the CInt.. Just tried that to see if that worked around the error.
