Question

我有包含用户数据的数据输入表（ServiceData）。列是Userid，BillDate（类型DateTime）等。我需要每周（当前一周）获取用户数。

查询

select     BillDate
          ,DATENAME(dw,BillDate) as day 
          ,count(BillDate) as total 
from ServiceData 
group by 
BillDate,DATENAME(dw,BillDate) 
order by BillDate desc

这只是获取日期，但是我想获取星期日入场计数，星期一入场计数....从星期日到星期六（当前每周）是可能的吗？

预期产量

    ID   |   TOTAL  |   DAY
   --------------------------
    1    |    23    |   Sun
    2    |    54    |   Mon
    3    |    17    |   Tues
    4    |    56    |   Thus
    5    |    45    |   Fri
    6    |    78    |   Sat

Answer 1

这应该可以解决问题：

SELECT 
  row_number() over (order by (SELECT 1)) ID,
  count(*) Total,
  LEFT(Datename(weekday, Cast(Billdate as date)), 3) Day
FROM 
  ServiceData
WHERE
  BillDate >= dateadd(week, datediff(d, -1, getdate()-2)/7, -1)
GROUP BY
  Cast(Billdate as date)
ORDER BY
  Cast(Billdate as date)

如何在sql server中获取本周的每日数据
