如何使用数据透视函数，使用日期部分字段

Question

Current Output

WeekNumber WeeklyCount 11 100 10 200 9 300 8 400 7 500

Desired Output

WeekNumber   11  10   9   8   7
WeeklyCount 100 200 300 400 500

Current query:

SELECT Top 5     DatePart(ww, DATE) as weekNumber, Count(id) as WeeklyCount
    FROM         dbo.AL
   Where DatePart(ww, DATE) <> DatePart(ww, GetDate())
    group by  DatePart(ww, DATE)
    order by DatePart(ww, DATE) desc

How do I use the pivot function to return the desired output?

Pivot function query

Answer 1

试试这个：

SELECT [11], [10], [9], [8], [7]
FROM (YourQueryHERE) AS DT
PIVOT(SUM(WeeklyCount) FOR WeekNumber IN([11], [10], [9], [8], [7])) AS PT
