Question

我用它来获取每周不同RepID的序列号和数量。但不是序列号（1,2,3），我希望序列号值为第1周，第2周，第3周。怎么可能？这是使用SQL Server 2005.谢谢！

Select ROW_NUMBER() OVER (ORDER BY Date) As SlNo, count(distinct(RepID))
from Reptable   
where Month(Date) = @Month
group by Datepart(week, Date)

Answer 1

您需要做的只是将cast() row_number作为字符串，然后在其开头连接Week：

Select 
  'Week ' + cast(ROW_NUMBER() OVER (ORDER BY Date) as varchar(10)) As SlNo, 
  count(distinct(RepID))
from Reptable   
where Month(Date) = @Month
group by Datepart(week, Date)

查询中以周数形式的序列号
