Tsql 如何从SQL Server CTE设置参数值？

给定以下SQL：

;WITH Results AS
    (
        SELECT ItemListID, Title,  
        ROW_NUMBER() OVER(ORDER BY ItemListID DESC) as intRow, 
        COUNT(ItemListID) OVER() AS ActualNumberOfResults 
        FROM ItemData
        WHERE FREETEXT(Title, @FTSSearchTerm)
        AND WebsiteID = @WebsiteID
        AND ContentTypeID = @ContentTypeID
        AND GeoID2 = @GeoID                                 
     )
SELECT * FROM Results
WHERE intRow BETWEEN @intStartRow AND @intEndRow
ORDER BY ItemListID DESC    

SELECT @NumberOfResultsReturned = @@ROWCOUNT

我想将参数@ActualNumberOfResults设置为从CTE返回的TOP（1）ActualNumberOfResults的值

在CTE之后，我使用了以下内容，但似乎是重复的：

SELECT @ActualNumberOfResults = COUNT(*)
FROM ItemData
WHERE CONTAINS(Title, @FTSSearchTerm  )
AND WebsiteID=@WebsiteID

我如何才能做到这一点？

        SELECT ItemListID, Title,  
        ROW_NUMBER() OVER(ORDER BY ItemListID DESC) as intRow, 
        COUNT(ItemListID) OVER() AS ActualNumberOfResults 
        FROM ItemData
        WHERE FREETEXT(Title, @FTSSearchTerm)
        AND WebsiteID = @WebsiteID
        AND ContentTypeID = @ContentTypeID
        AND GeoID2 = @GeoID                                 
     )
SELECT * FROM Results
WHERE intRow BETWEEN @intStartRow AND @intEndRow
ORDER BY ItemListID DESC   

SELECT @NumberOfResultsReturned = @@ROWCOUNT

;WITH Results1 AS
    (
        SELECT ItemListID, Title,  
        ROW_NUMBER() OVER(ORDER BY ItemListID DESC) as intRow, 
        COUNT(ItemListID) OVER() AS ActualNumberOfResults 
        FROM ItemData
        WHERE FREETEXT(Title, @FTSSearchTerm)
        AND WebsiteID = @WebsiteID
        AND ContentTypeID = @ContentTypeID
        AND GeoID2 = @GeoID                                 
     )

SELECT @ActualNumberOfResults = COUNT(*)
FROM Results1
