窓関数を使用して合計数を取得します

Question

ちょっとこれはすべてのクエリは、私がこれまで持っている：

WITH LIMIT AS 
     (SELECT 
      U.userID 
      ,U.username 
      ,U.fname  
      ,U.mname  
      ,U.lname  
      ,U.email  
      ,U.active 
      ,S.sName 
      ,S.sID 
      ,T.[value] 
      ,T.trackingNumberID 
      ,SU.primaryLocation 
      ,row_number() OVER (ORDER BY U.userid) AS RN 
      ,COUNT(*) OVER (ORDER BY U.userid) AS CNT 
      ,UR.roleID 
     FROM 
      [---].[dbo].[tblUsers]       AS U 
     LEFT OUTER JOIN [---].[dbo].[tblTrackingNumbers] AS T 
      ON T.userID = U.userID 
     LEFT OUTER JOIN [---].[dbo].[tblSU]     AS SU 
      ON U.userID = SU.userID 
     LEFT OUTER JOIN [---].[dbo].[tblS]     AS S 
      ON SU.sID = S.sID 
     LEFT OUTER JOIN [---].[dbo].[tblUserRoles]   AS UR 
      ON UR.userID = U.userID 
     LEFT OUTER JOIN [---].[dbo].[tblRoles]    AS R 
      ON UR.roleID = R.roleID 
     WHERE 
      U.active = 1 
     AND 
      SU.primaryLocation = 1 
     AND 
      SU.active = 1 
     AND 
       U.orgID = 1 
      AND 
       S.ID = 35 
      AND U.userID IN (SELECT userID 
           FROM [---].[dbo].[tblSU] AS SU 
           INNER JOIN [].[dbo].[tblS] AS S 
           ON S.sID = SU.sID 
           WHERE 
           SU.active = 1 
           AND 
           S.sID = 35) 
) SELECT * FROM LIMIT WHERE RN Between 0 AND 10000 

私はU. BY COUNT（*）OVER（ORDERをしようとしています上記のクエリで見ることができるようにユーザーID）AS CNTこれは私にと同じカウントを与えるRNです。私は必要なもの

は、このバック（842行）をもたらすことになるの記録の総量です。

Answer 1

は、「実行中のカウント」 - 「その」行までのカウントを調整します。あなたは完全な結果のすべての行をカウントしたい場合は、これはカッコウを聞こえるかもしれないが、私はあなたが変数にカウント数を選択した場合、あなたがより良いパフォーマンスを得る大きなテーブルで発見され、order by

COUNT(*) OVER() AS CNT 

Answer 2

せずにウィンドウ関数を使用しますあなたのレコードを選択し、変数を追加するだけです。 count（*）over（）を持つものは、テーブルが大きすぎるとパフォーマンスが低下します。

DECLARE @RecordCount INT
