实施ROW_NUMBER（）到特定的查询

Question

我有以下查询，返回基于一些输入参数组的列：

WITH hierarchy AS (
    SELECT yt.id  
     FROM [dbo].[TH_Categories] yt 
     WHERE yt.ID = @topicID And CultureID = @cultureID 
    UNION ALL 
    SELECT yt.id  
     FROM [dbo].[TH_Categories] yt 
     JOIN hierarchy h ON h.ID = yt.ParentCategoryID) 
    Select id, 
      [SiteName] 
      ,[SiteURL] 
      ,[Description] 
      ,[Logo] 
      ,[CultureID] 
      ,[DateAdded], 
      dbo.GetSiteFollowers(id) AS Followers 
    from dbo.TH_Sites 
    where id in (Select Distinct SiteID 
        from dbo.TH_CategoryFeeds 
        Where CatID in (SELECT ID 
            FROM hierarchy t)) 

我试图实现使用ROW_NUMBER（）函数分页，但我无法找到方法。

任何帮助将高度赞赏它。

试试这个：

;WITH hierarchy AS 
(
    SELECT yt.id  
     FROM [dbo].[TH_Categories] yt 
     WHERE yt.ID = @topicID And CultureID = @cultureID 
    UNION ALL 
    SELECT yt.id  
     FROM [dbo].[TH_Categories] yt 
     JOIN hierarchy h ON h.ID = yt.ParentCategoryID 
) 
, YourRows AS 
(
    Select id, 
      [SiteName] 
      ,[SiteURL] 
      ,[Description] 
      ,[Logo] 
      ,[CultureID] 
      ,[DateAdded] 
      ,dbo.GetSiteFollowers(id) AS Followers 
      ,ROW_NUMBER() OVER (ORDER BY ActivityDate DESC) AS RowNumber 
    from dbo.TH_Sites 
    where id in (Select Distinct SiteID 
        from dbo.TH_CategoryFeeds 
        Where CatID in (SELECT ID 
            FROM hierarchy t)) 
) 
SELECT * FROM YourRows 
WHERE RowNumber>=@Start and RowNumber<=@End
