count语句支持*、列名、常量、变量,并且可以用distinct关键字修饰， 并且count(列名)不会累计null的记录。下面随便用一些例子示范一下count的规则：比如对如下表做统计，所有列这里都用sql_variant类型来表示。
if (object_id ('t_test' )> 0 )
drop table t_test
go
create table t_test (a ......
表中主键必须为标识列，[ID] int IDENTITY (1,1)
1.分页方案一：(利用Not In和SELECT TOP分页)
语句形式：
SELECT TOP 页记录数量 *
from 表名
WHERE (ID NOT IN
(SELECT TOP (每页行数*(页数-1)) ID
from 表名
ORDER BY ID))
ORDER BY ID
//自己还可以加上一些查询 ......
