分页查询的方法已经很多很多，在这里我也加入成为其中一员。
SQL Server中有一个Set Rowcount的的设置，它的意思是使命令的处理在响应指定的行数之后停止处理命令，利用这个特点，我们可以借用它来在一个千万行级数据表中实现高性能分页查询。先来说说实现方式：
1、我们来假定Table中有一个已经建立了索引的主键字段ID（整数型），我们将按照这个字段来取数据进行分页。
2、页的大小我们放在@PageSize中
3、当前页号我们放在@CurrentPage中
4、如何让记录指针快速滚动到我们要取的数据开头的那一行呢，这是关键所在！有了Set RowCount，我们就很容易实现了。
5、如果我们成功地滚动记录指针到我们要取的数据的开头的那一行，然后我们把那一行的记录的ID字段的值记录下来，那么，利用Top和条件，我们就很容易的得到指定页的数据了。当然，有了Set RowCount，我们难道还用Top么？
看看Set Rowcount怎么来帮我们的忙吧：

Declare @ID int
Declare @MoveRecords int

--@CurrentPage和@PageSize是传入参数
Set @MoveRecords=@CurrentPage * @PageSize+1

--下面两行实现快速滚动到我们要取的数据的行，并把ID记录下来
Set Rowcount @MoveRecords
Select @ID=ID from Table1 Order by ID

Set Rowcount @PageSize
--最恨为了减少麻烦使用*了，但是在这里为了说明方便，暂时用一下
Select * From Table1 Where ID>=@ID Order By ID
Set Rowcount 0
大家可以试试看，在一个1千W记录的表里面，一下子方翻页到第100页（每页100条），看看有多快！
