1.创建表

create table datas(
id int,
userid varchar(30),
data int,
rdate datetime
);

2.添加数据

insert into datas(id,userid,data,rdate) values(1,'1',1,'2009-10-26 16:01:00');
insert into datas(id,userid,data,rdate) values(2,'1',1,'2009-10-26 16:02:00');
insert into datas(id,userid,data,rdate) values(3,'1',1,'2009-10-26 16:03:00');
insert into datas(id,userid,data,rdate) values(4,'1',1,'2009-10-26 16:04:00');
insert into datas(id,userid,data,rdate) values(5,'1',1,'2009-10-26 16:05:00');
insert into datas(id,userid,data,rdate) values(6,'1',1,'2009-10-26 16:06:00');
insert into datas(id,userid,data,rdate) values(7,'1',1,'2009-10-26 16:08:00');
insert into datas(id,userid,data,rdate) values(8,'1',1,'2009-10-26 16:09:00');
insert into datas(id,userid,data,rdate) values(9,'1',1,'2009-10-26 16:10:00');
insert into datas(id,userid,data,rdate) values(10,'1',1,'2009-10-26 16:11:00');
insert into datas(id,userid,data,rdate) values(11,'1',1,'2009-10-26 16:15:00');
insert into datas(id,userid,data,rdate) values(12,'1',1,'2009-10-26 16:16:00');
insert into datas(id,userid,data,rdate) values(13,'1',1,'2009-10-27 16:01:00');
insert into datas(id,userid,data,rdate) values(14,'1',1,'2009-10-27 16:02:00');
insert into datas(id,userid,data,rdate) values(15,'1',1,'2009-10-27 16:03:00');
insert into datas(id,userid,data,rdate) values(16,'1',1,'2009-10-27 16:04:00');
insert into datas(id,userid,data,rdate) values(17,'1',1,'2009-10-27 16:05:00');
insert into datas(id,userid,data,rdate) values(18,'1',1,'2009-10-27 16:06:00');
insert into datas(id,userid,data,rdate) values(19,'1',1,'2009-10-27 16:56:00');
insert into datas(id,userid,data,rdate) values(20,'1',1,'2009-10-27 16:58:00');
insert into datas(id,userid,data,rdate) values(21,'1',1,'2009-10-27 17:00:00');

3.select SQL文
