insert into tb values('2007-1-1 10:08:00' ,          1 )

insert into tb values('2007-1-1 10:12:11' ,          5 )

go

select dateadd(mi,(datediff(mi,convert(varchar(10),dateadd(ss,-1,时间),120),dateadd(ss,-1,时间))/5)*5,convert(varchar(10),时间,120)) as 时间段,

       count(*) as 行数,

       sum(金额) as 总金额

from tb

group by dateadd(mi,(datediff(mi,convert(varchar(10),dateadd(ss,-1,时间),120),dateadd(ss,-1,时间))/5)*5,convert(varchar(10),时间,120))
