/*创建表*/
create table tb(
km_h int,
zkzh int,
ss_h int,
zw_h int
)
//科目号|考生编号|室试号|座位号
//1    158994    590    94

drop table tb;        //删除表数据和表结构
delete  from tb;    //删除表数据，保留表结构
select * from tb;    //查询表数据

/*使用sql server插入100万数据*/
declare @zkzh int,
        @ss_h int,
        @zw_h int;
set @zkzh=100001;
while @zkzh<=1100000
begin
    set @ss_h=1;
    while @ss_h<=10000
    begin
        set @zw_h=1;
        while @zw_h<=100
        begin
            insert into bigdata.dbo.tb(km_h,zkzh,ss_h,zw_h) values(1,@zkzh,@ss_h,@zw_h);
            set @zw_h=@zw_h+1;
            set @zkzh=@zkzh+1;
        end;
    set @ss_h=@ss_h+1;
    end;
end;

下面是分页查询代码：
这里只记录了性能最好的一种：原文地址：https://www.cnblogs.com/xiaoMzjm/p/3933077.html

select * from (
     select *,row_number() 
     over(order by zkzh desc)n from tb
	 )hhh 
	 where hhh.n>50000 and hhh.n<=50010
