Sqlserver数据库分页查询一直是Sqlserver的短板，闲来无事，想出几种方法，假设有表ARTICLE,字段ID、YEAR...(其他省略)，数据53210条(客户真实数据，量不大)，分页查询每页30条，查询第1500页（即第45001-45030条数据），字段ID聚集索引，YEAR无索引，Sqlserver版本：2008R2
第一种方案、最简单、普通的方法：
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
平均查询100次所需时间：45s
第二种方案：
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
平均查询100次所需时间：138S
第三种方案：
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
平均查询100次所需时间：21S
第四种方案：
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
平均查询100次所需时间：20S
第五种方案：
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
平均查询100次所需时间：15S
查询第1000-1030条记录
第一种方案：
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
平均查询100次所需时间：80s
第二种方案：
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
平均查询100次所需时间：30S
第三种方案：
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
平均查询100次所需时间：12S
第四种方案：
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
平均查询100次所需时间：13S
第五种方案：
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
平均查询100次所需时间：14S
由此可见在查询页数靠前时，效率3>4>5>2>1，页码靠后时5>4>3>1>2，再根据用户习惯，一般用户的检索只看最前面几页，因此选择3 4 5方案均可，若综合考虑方案5是最好的选择，但是要注意SQL2000不支持row_number()函数，由于时间和条件的限制没有做更深入、范围更广的测试，有兴趣的可以仔细研究下。
以下是根据第四种方案编写的一个分页存储过程：
