上周﹐被一位網友問到在sql2000中，想選取一張表的第Ｎ條記錄怎麼寫?(即如下語句select ID,Name,Title from WebSite order by ID desc 如何改寫以達到目的)
我當時直接就給他回
select ID,Name,Title from WebSite where ID= N
最后這位老兄說如果是ＩＤ是連續的話就可以，如果有記錄刪除的話，ＩＤ不連續了，就不行了 ,至此才明白他的真正意思。剛好要輪到公司的周會時間﹐于是想了一下。給出如下答案給他﹕

-- select top 1 [ID],[Name,Title from WebSite
-- where not [ID] in (select top 11 [ID] from WebSite order by [ID] asc) order by [ID] asc
Declare @strSql Varchar(200),@intTopN int
Set @intTopN = 11
Set @strSql = 'select top 1 [ID],[Name,Title from WebSite where not [ID] in (select top '+Cast(@intTopN As Varchar(10))+' [ID] from WebSite order by [ID] asc) order by [ID] asc'
Print @strSql
Exec(@strSql)

做完之后﹐總感覺應該會有更好的解決方案﹐可又一時想不出來!將其放在這里﹐供各位討論拍磚﹐如有最佳方案也請網友們不吝指教!

SELECT TOP 11 * FROM
(
SELECT Name,Title,
(SELECT COUNT(*) FROM WebSite WHERE id< w.id) AS c
FROM WebSite AS w
)
ORDER BY c

樓上的果然高明﹕按照那個網友的意思﹐我整理了一下﹕
SELECT * FROM
(
SELECT [ID], [Name],[Title]
(SELECT COUNT(*) FROM WebSite WHERE [ID]< w.[ID]) AS c
FROM WebSite AS w
) AS A WHERE c = 11 ORDER BY c ASC

Or
Declare @intTopN int
Set @intTopN = 12
SELECT * FROM
(
SELECT [ID], [Name],[Title]
(SELECT COUNT(*) FROM WebSite WHERE [ID]< w.[ID]) AS c
FROM WebSite AS w
) AS A WHERE c = @intTopN -1 ORDER BY c ASC

請問一下，你寫的這段語句“
SELECT * FROM
(
SELECT [ID], [Name],[Title]
(SELECT COUNT(*) FROM WebSite WHERE [ID]< w.[ID]) AS c
FROM WebSite AS w
) AS A WHERE c = 11 ORDER BY c ASC
”
取得是第12筆的記錄而不是第11筆的吧？？？？？
