sql查詢中的總行數--- sql server 2008

Question

我的查詢如下

BEGIN

    WITH MyCTE
    AS (
        SELECT T.MusicAlbumTitle
            ,D.musicTitle
            ,D.mVideoID
            ,D.musicFileName
            ,T.ReleaseDate AS ReleasedDate
            ,D.MusicLength
            ,D.musicSinger
            ,D.MusicVideoID
            ,D.ExternalLink             
            ,D.CoverImg             
            ,ROW_NUMBER() OVER (
                PARTITION BY D.MusicVideoID ORDER BY D.mVideoID
                ) AS row_num
        FROM dbo.Music_Video T
        JOIN dbo.Music_Video_Details D ON T.MusicVideoID = D.MusicVideoID
        WHERE T.PortalID = @PortalID
            AND T.CultureCode = @CultureCode
            AND T.ComingSoon <> 1
        GROUP BY T.MusicAlbumTitle
            ,D.musicTitle
            ,D.mVideoID
            ,T.ReleaseDate
            ,D.musicFileName
            ,D.MusicLength
            ,D.musicSinger
            ,D.MusicVideoID
            ,D.ExternalLink
            ,D.CoverImg
        )   
    SELECT a.mVideoID
        ,a.MusicVideoID
        ,a.musicFileName            
        ,a.MusicAlbumTitle
        ,a.ReleasedDate
        ,a.row_num
        ,a.CoverImg
        ,a.ExternalLink         
        ,a.musicTitle
        ,a.MusicLength                  
    FROM MyCTE a            
    WHERE row_num = 1
    ORDER BY MusicVideoID DESC
END

我需要從上一個select語句中獲得總行數。 這意味着正在選擇的總行數。

或任何可能在這種情況下使用的想法

我怎樣才能做到這一點 ..

Answer 1

請在您的選擇中添加COUNT(*) OVER() ，這將返回選為新列的總行數。 例如：

SELECT 
    *, 
    COUNT(*) OVER() AS [Total_Rows] 
FROM YourTable

Answer 2

為了清楚起見，您需要將計數添加到CTE，而不是外部查詢。 外部選擇只返回一行，因此計數總是一行。

CTE應該開始：

WITH MyCTE
AS (
    SELECT T.MusicAlbumTitle
        ,D.musicTitle
        ,D.mVideoID
        ,D.musicFileName
        ,T.ReleaseDate AS ReleasedDate
        ,D.MusicLength
        ,D.musicSinger
        ,D.MusicVideoID
        ,D.ExternalLink             
        ,D.CoverImg             
        ,ROW_NUMBER() OVER (
            PARTITION BY D.MusicVideoID ORDER BY D.mVideoID
            ) AS row_num,
        COUNT(*) over () as total_count
