如何计算SQL Server中具有不同范围的行来计算范围内的记录

Question

SELECT Distinct 
    m_KioskInformationHdr.kioskID,m_KioskInformationHdr.agency,
    m_KioskInformationHdr.kioskIP,
    COUNT(distinct m_KioskInformationHdr.KioskID) as NoDT
from
    m_KioskInformationHdr
inner join 
    t_KioskStatus ON t_kioskStatus.kioskID = m_KioskInformationHdr.kioskID
where
    t_KioskStatus.IsOpen = 1 
    and DatePost between '2014-01-20 00:00:00' and '2014-01-21 23:59:59'
group by 
    t_KioskStatus.DatePost, m_KioskInformationHdr.kioskID,
    m_KioskInformationHdr.kioskIP, m_KioskInformationHdr.agency

我想要这个输出：

01254878 | PHilippines,Pasig | 192.168.2.8 | 2

这是我目前的输出：

01254878 | PHilippines,Pasig | 192.168.2.8 | 1
01254878 | PHilippines,Pasig | 192.168.2.8 | 1

我该如何进行此查询？
