常用SQL Server分页方式

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 

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 

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 

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 

第五种方案：

SELECT w2.n
       ,w1.*
  FROM ( SELECT TOP 50030 Row_number() OVER (ORDER BY YEAR DESC, ID DESC) n
                          ,ID
           FROM ARTICLE ) w2
       ,ARTICLE w1
 WHERE w1.ID = w2.ID
       AND w2.n > 50000
 ORDER BY w2.n ASC 

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
