Tsql 如何在此查询中使用Count子句？

我有一个相当昂贵的查询，返回一页结果：

SELECT * FROM 
    (SELECT         
        ROW_NUMBER() OVER (ORDER BY j.PostDate DESC) as Row,                                            
        FROM 
            JobListing j, 
            Location l, 
            City c,
            JobListing_Skill_XREF js,
            @SkillTable st            
        WHERE 
            DistanceBetween(@lat,@long, c.Lat,c.Long) <= @miles AND
            js.Skill_ID = st.id AND                     
            j.location = l.id AND
            j.id = js.JobListing_Id AND         
            l.CityID = c.Id             
    ) AS RESULTS
    WHERE Row Between (@PageNumber - 1) * @PageSize + 1 and (@PageNumber * @PageSize)

我想做的是返回内部查询的总计数，以便计算总页数

然而，我不知道如何将COUNT子句穿入其中，我真的不想将其选择到临时表中，或者只为了计算页面计数而运行两次

有什么想法吗？

用一个？像这样的东西显然无法测试：

WITH R (Row) 
AS 
(
  SELECT                                 
  ROW_NUMBER() OVER (ORDER BY j.PostDate DESC) as Row,
  FROM JobListing j, Location l, City c, JobListing_Skill_XREF js,@SkillTable st
  WHERE DistanceBetween(@lat,@long, c.Lat,c.Long) <= @miles AND 
    js.Skill_ID = st.id AND
    j.location = l.id AND
    j.id = js.JobListing_Id AND
    l.CityID = c.Id      
)
SELECT R.*, COUNT(R.*) AS [Count] FROM R
WHERE R.Row Between (@PageNumber - 1) * 
  @PageSize + 1 and (@PageNumber * @PageSize)

    l.CityID = c.Id      
)
SELECT R.*, COUNT(R.*) AS [Count] FROM R
WHERE R.Row Between (@PageNumber - 1) * 
  @PageSize + 1 and (@PageNumber * @PageSize)

这是我能做的最好的，我想知道人们是否有更好的建议：

DECLARE @JobTable TABLE
(
    ...snip...
);
INSERT INTO @JobTable 
    SELECT          
        ROW_NUMBER() OVER (ORDER BY j.PostDate DESC) as Row,
        j.*                     
        FROM 
            JobListing j, 
            Location l, 
            City c,
            JobListing_Skill_XREF js,
            @SkillTable st            
        WHERE 
            DistanceBetween(@lat,@long, c.Lat,c.Long) <= @miles AND
            js.Skill_ID = st.id AND                     
            j.location = l.id AND
            j.id = js.JobListing_Id AND         
            l.CityID = c.Id 

SELECT * 
         FROM @JobTable
         WHERE 
               Row BETWEEN 
                 (@PageNumber - 1) * @PageSize + 1 
                 AND (@PageNumber * @PageSize)


SELECT @TotalRows = Count(1) FROM @JobTable;
