Sqlserver數據庫分頁查詢一向是Sqlserver的短板，閒來無事，想出幾種辦法，假定有表ARTICLE,字段ID、YEAR...(其他省略)，數據53210條(客戶真實數據，量不年夜)，分頁查詢每頁30條，查詢第1500頁（即第45001-45030條數據），字段ID集合索引，YEAR無索引，Sqlserver版本：2008R2
第一種計劃、最簡略、通俗的辦法：
SELECT TOP 30 * FROM ARTICLE WHERE ID NOT IN(SELECT TOP 45000 ID FROM ARTICLE ORDER BY YEAR DESC, ID DESC) ORDER BY YEAR DESC,ID DESC
均勻查詢100次所需時光：45s
第二種計劃：
SELECT * FROM ( SELECT TOP 30 * FROM (SELECT TOP 45030 * FROM ARTICLE ORDER BY YEAR DESC, ID DESC) f ORDER BY f.YEAR ASC, f.ID DESC) s ORDER BY s.YEAR DESC,s.ID DESC
均勻查詢100次所需時光：138S
第三種計劃：
SELECT * FROM ARTICLE w1,
(
SELECT TOP 30 ID FROM
(
SELECT TOP 50030 ID, YEAR FROM ARTICLE ORDER BY YEAR DESC, ID DESC
) w ORDER BY w.YEAR ASC, w.ID ASC
) w2 WHERE w1.ID = w2.ID ORDER BY w1.YEAR DESC, w1.ID DESC
均勻查詢100次所需時光：21S
第四種計劃：
SELECT * FROM ARTICLE w1
WHERE ID in
(
SELECT top 30 ID FROM
(
SELECT top 45030 ID, YEAR FROM ARTICLE ORDER BY YEAR DESC, ID DESC
) w ORDER BY w.YEAR ASC, w.ID ASC
)
ORDER BY w1.YEAR DESC, w1.ID DESC
均勻查詢100次所需時光：20S
第五種計劃：
SELECT w2.n, w1.* FROM ARTICLE w1, (
SELECT TOP 50030 row_number() OVER (ORDER BY YEAR DESC, ID DESC) n, ID FROM ARTICLE
) w2 WHERE w1.ID = w2.ID AND w2.n > 50000 ORDER BY w2.n ASC
均勻查詢100次所需時光：15S
查詢第1000-1030筆記錄
第一種計劃：
SELECT TOP 30 * FROM ARTICLE WHERE ID NOT IN(SELECT TOP 1000 ID FROM ARTICLE ORDER BY YEAR DESC, ID DESC) ORDER BY YEAR DESC,ID DESC
均勻查詢100次所需時光：80s
第二種計劃：
SELECT * FROM (
SELECT TOP 30 * FROM (SELECT TOP 1030 * FROM ARTICLE ORDER BY YEAR DESC, ID DESC) f ORDER BY f.YEAR ASC, f.ID DESC
) s ORDER BY s.YEAR DESC,s.ID DESC
均勻查詢100次所需時光：30S
第三種計劃：
SELECT * FROM ARTICLE w1,
(
SELECT TOP 30 ID FROM
(
SELECT TOP 1030 ID, YEAR FROM ARTICLE ORDER BY YEAR DESC, ID DESC
) w ORDER BY w.YEAR ASC, w.ID ASC
) w2 WHERE w1.ID = w2.ID ORDER BY w1.YEAR DESC, w1.ID DESC
均勻查詢100次所需時光：12S
第四種計劃：
SELECT * FROM ARTICLE w1
WHERE ID in
(
SELECT top 30 ID FROM
(
SELECT top 1030 ID, YEAR FROM ARTICLE ORDER BY YEAR DESC, ID DESC
) w ORDER BY w.YEAR ASC, w.ID ASC
)
ORDER BY w1.YEAR DESC, w1.ID DESC
均勻查詢100次所需時光：13S
第五種計劃：
SELECT w2.n, w1.* FROM ARTICLE w1,(
SELECT TOP 1030 row_number() OVER (ORDER BY YEAR DESC, ID DESC) n, ID FROM ARTICLE
) w2 WHERE w1.ID = w2.ID AND w2.n > 1000 ORDER BY w2.n ASC
均勻查詢100次所需時光：14S
因而可知在查詢頁數靠前時，效力3>4>5>2>1，頁碼靠後時5>4>3>1>2，再依據用戶習氣，普通用戶的檢索只看最後面幾頁，是以選擇3 4 5計劃都可，若綜合斟酌計劃5是最好的選擇，然則要留意SQL2000不支撐row_number()函數，因為時光和前提的限制沒有做更深刻、規模更廣的測試，有興致的可以細心研討下。
以下是依據第四種計劃編寫的一個分頁存儲進程：
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sys_Page_v2]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[sys_Page_v2]
GO

SET @SqlCount = 'SELECT @RCount=COUNT(1),@PCount=CEILING((COUNT(1)+0.0)/'

EXEC SP_EXECUTESQL @SqlCount,N'@RCount INT OUTPUT,@PCount INT OUTPUT',
@RCount OUTPUT,@PCount OUTPUT
IF @sys_PageIndex > CEILING((@RCount+0.0)/@sys_PageSize) --假如輸出確當前頁數年夜於現實總頁數,則把現實總頁數賦值給以後頁數

print(@sql)
Exec(@sql)
GO
