/* 楼主太懒了,给的表没用的字段都给了~~ 思路就是以下面的方式 如果不想给出指定的时间,用游标一条一条去判断是不是在这个时间范围之类。如果日期乱的话就没办法。 */ insert into WarnUse values ('0001','225779','EM','2010-07-23 15:45:14.000',null,null,null) insert into WarnUse values ('0001','225779','EM','2010-07-23 16:00:16.000',null,null,null) insert into WarnUse values ('0001','225779','EM','2010-07-24 19:45:17.000',null,null,null) insert into WarnUse values ('0001','225779','EM','2010-07-25 20:45:14.000',null,null,null) insert into WarnUse values ('0001','225779','EM','2010-07-25 20:00:16.000',null,null,null) insert into WarnUse values ('0001','225779','EM','2010-07-24 20:45:17.000',null,null,null) declare @SDT datetime,@EDT datetime set @SDT ='2010-07-25 20:00:00.000' set @EDT ='2010-07-25 21:00:00.000' select COUNT(*) from WarnUse where DATime between @SDT and @EDT ----------- 2 (1 row(s) affected) 没有看明白楼主怎么把这个值传到另外一个表里面去

insert into WarnCount(DADay,DANo,DAHour,SumQty)
select convert(varchar(8),DATime,112),convert(varchar(8),DATime,112)+convert(varchar(2),getdate(),108),convert(varchar(2),getdate(),108),count(1)
from WarnUse convert(varchar(8),DATime,112),convert(varchar(8),DATime,112)+convert(varchar(2),getdate(),108),convert(varchar(2),getdate(),108)
