/*create table bw24417
(
[date] datetime,
accountid varchar(20),
logincount int
)
insert into bw24417 values (GETDATE(),'1',1);
insert into bw24417 values (GETDATE(),'3',1);
insert into bw24417 values (GETDATE(),'1',1);
insert into bw24417 values (GETDATE(),'1',1);
insert into bw24417 values (GETDATE(),'2',1);
insert into bw24417 values (GETDATE(),'1',1);
insert into bw24417 values (GETDATE(),'2',1);
insert into bw24417 values (GETDATE(),'4',1);
insert into bw24417 values (GETDATE(),'3',1);
insert into bw24417 values (GETDATE(),'4',1);
insert into bw24417 values (GETDATE(),'3',1);
*/
select * from bw24417;
select accountid,count(logincount) AS huoyue from bw24417 where DATEDIFF(day,[date],GETDATE())<7 group by accountid having count(logincount)>2;
结果：
date accountid logincount

SQL语句中的数字7改为你想要的就OK了啊
可能是我没有表达明白,我说的最近七天,不是与当前日期相对,不是getdate()-7,而是登录日期-7.譬如,我要计算2011-04-25那天的活跃用户数,则是 date between @date-6 and @date .
你用这个：date between @date-6 and @date替换DATEDIFF(day,[date],GETDATE())<7就好了啊，如果写成存储过程就把@date作为一个参数传进来，否则就拼接一个SQL语句就好了啊
呀,你应该在自己的机子上运行下看看结果,需要另外一个表,来表示时间区间,否则是做不出来的.
某段时间，这个时间是业务上的问题，至于这个时间区间是放在另一张表中还是从配置文件中读取都没关系不，只要按照上面的语句稍加修改就可以用了，我不明白你到底指的是什么意思
这是我最后的结果 不过仍然感谢你的回答
