SQL Server CTE에서 매개 변수 값을 설정하는 방법은 무엇입니까?

Question

는 다음과 같은 SQL을 감안할 때 :

;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 

내가 매개 변수를 설정하려는, TOP의 값 @ActualNumberOfResults (1) CTE에서 반환 ActualNumberOfResults.

내가 사용하여 CTE 후, 다음,하지만 반복적 인 것 같다

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

가 어떻게 이러한 목표를 달성 할 수 있습니까? 에

;WITH cte AS 
(
    SELECT ItemListID, Title, 
     CASE WHEN ROW_NUMBER() OVER(ORDER BY ItemListID DESC) 
        BETWEEN @intStartRow AND @intEndRow THEN 1 
        END AS NumberOfResultsReturned,  
     COUNT(ItemListID) OVER() AS ActualNumberOfResults   
    FROM ItemData 
    WHERE FREETEXT(Title, @FTSSearchTerm) 
     AND WebsiteID = @WebsiteID 
     AND ContentTypeID = @ContentTypeID 
     AND GeoID2 = @GeoID         
) 
SELECT @NumberOfResultsReturned = COUNT(NumberOfResultsReturned), 
     @ActualNumberOfResults = MAX(ActualNumberOfResults) 
FROM cte

SELECT * FROM Results 
WHERE intRow BETWEEN @intStartRow AND @intEndRow 
ORDER BY ItemListID DESC 

SELECT @NumberOfResultsReturned = @@ROWCOUNT 

;WITH Results1 AS

SELECT @ActualNumberOfResults = COUNT(*)
