Question

我有100条记录，我可以使用查询中的“TOP 10”选择前10名。同样有什么可以获得20到30的记录？

Answer 1

由于您使用的是SQL Server 2005，因此可以使用“new”ROW_NUMBER（）函数。这将为您提供第11至20行：

SELECT  Description, Date
FROM     (SELECT  ROW_NUMBER() OVER (ORDER BY Date DESC)
             AS Row, Description, Date FROM LOG)
            AS LogWithRowNumbers
WHERE  Row >= 11 AND Row <= 20

如果你有很多记录，在内部SELECT子句中使用TOP X可能会加速一些事情，因为如果你只想抓取11到20的记录，就没有用来返回1000条记录：

SELECT  Description, Date
FROM     (SELECT TOP 20 ROW_NUMBER() OVER (ORDER BY Date DESC)
             AS Row, Description, Date FROM LOG)
            AS LogWithRowNumbers
WHERE  Row >= 11 AND Row <= 20

您应该使用ROWNUMBER（）获取结果集的记录数，并在原因中过滤它。

SELECT * FROM   (SELECT ROW_NUMBER() OVER(ORDER BY name) AS
rownum, name , age FROM Table) AS Table1
WHERE rownum >= 2 AND rownum <= 5

----------------------------
rownum     | name |   age   |
----------------------------
   2     |John    |   25    | 
   3     |Adam    |   23    | 
   4     |Tom     |   19    |
   5     |Jame    |   22    |
----------------------------

类似于TOP 10的查询选择中间记录？
