sql循环结果/分组依据/排序

这是我上一篇文章的后续问题

我有下面的代码，它将查询我们的代理在特定时间登录的数据库。它在给定的一天内运行良好，但我现在需要在选定的时间段内执行它。我不知道从哪里开始调整这个！我需要按日期和时间分组的结果。。。因此，它将如下所示

date        hour    count
10/10/11    22      52
10/10/11    23      24
11/10/11    00      12
11/10/11    01      33

因此，所选范围内的每个日期都将显示24小时周期

ALTER procedure [dbo].[LoggedOnCountByHour]
    @DayToCheck datetime,
    @HelplineID int
as

select  dateadd(hour, N.number, @DayToCheck) as [date_hour], 
        DATEPART(hh,dateadd(hour, N.number, @DayToCheck)) as [Hour],
        count(L.ExpertRecID) as [count of users]
from master..spt_values as N
  left outer join WorkDetail as L
    on L.KickedOffTime > dateadd(hour, N.number, @DayToCheck) and
       L.LoginTime < dateadd(hour, N.number + 1, @DayToCheck)
left join PoolMembership P on P.ExpertRecID = L.ExpertRecID

where N.Type = 'P' and
      N.Number between 0 and 23 and
      P.HelplinePoolID = @HelplineID 
group by dateadd(hour, N.number, @DayToCheck), DATEPART(hh,dateadd(hour, N.number, @DayToCheck) )

ALTER过程[dbo].[LoggedOnCountByHour]
@DayToCheck datetime，
@HelplineID int
作为
选择dateadd（hour，N.number，@DayToCheck）作为[日期\小时]，
DATEPART（hh，dateadd（hour，N.number，@DayToCheck））为[hour]，
计数（L.ExpertRecID）为[用户计数]
来自主..标准贯入度单位值为N
左外连接工作细节为L
在L.KickedOffTime>dateadd（小时、N.number、@DayToCheck）和
L.LoginTime

有什么想法吗！？ 非常感谢

诸如此类（未经彻底测试）

alter过程[dbo].[LoggedOnCountByHour]
@FromDay检查日期时间，
@今天检查日期时间，
@HelplineID int
作为
选择dateadd（hour，N.number，@FromDayToCheck）作为[date\u hour]，
DATEPART（hh，dateadd（hour，N.number，@FromDayToCheck））为[hour]，
计数（L.ExpertRecID）为[用户计数]
来自主..标准贯入度单位值为N
左外连接工作细节为L
在L.KickedOffTime>dateadd（小时、N.number、@FromDayToCheck）和
L.LoginTimedateadd（hour，N.number+1，@FromDayToCheck）为SQL Server 2000添加了标记。我猜你还是用这个对吧？
alter procedure [dbo].[LoggedOnCountByHour]
        @FromDayToCheck datetime,
        @ToDayToCheck datetime,
        @HelplineID int
as

select  dateadd(hour, N.number, @FromDayToCheck) as [date_hour], 
        DATEPART(hh,dateadd(hour, N.number, @FromDayToCheck)) as [Hour],
        count(L.ExpertRecID) as [count of users]
from master..spt_values as N
  left outer join WorkDetail as L
    on L.KickedOffTime > dateadd(hour, N.number, @FromDayToCheck) and
       L.LoginTime < dateadd(hour, N.number + 1, @FromDayToCheck)
  left join PoolMembership P on P.ExpertRecID = L.ExpertRecID

where N.Type = 'P' and
      dateadd(hour, N.number + 1, @FromDayToCheck) <= @ToDayToCheck + 1 and
      P.HelplinePoolID = @HelplineID 
group by dateadd(hour, N.number, @FromDayToCheck), DATEPART(hh,dateadd(hour, N.number, @FromDayToCheck) )
order by [date_hour], [Hour]
