sql - 查询中周数形式的序列号

Question

我用它来获取每周不同 RepID 的序列号和计数。但是我希望序列号值不是序列号（1、2、3），而是第 1 周、第 2 周、第 3 周。这怎么可能？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

您需要做的就是cast()作为row_number字符串，然后Week在它的开头连接：

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)
