我必须为所有人提供以下观点。

2014年9月

Resource Name   Days Booked ( Days Worked - Holidays )    Total Rate 
   Dave Y            6      ( 12 - 6)                          120

还有十月和十一月。

如何在一个查询中通过sql将丑陋的表转换为下表？

Answer 1

您需要说明总费率＆＃39;是来自。但这是完成其余部分的一种方法。

SELECT
    cast(Datepart(m, WeekStarting) as varchar(2)) + '/' + cast(Datepart(yyyy, WeekStarting) as varchar(4)) as [Month]
    , ResourceName
    , SUM (CASE WHEN PROJECT = 'HOLIDAY' THEN -1 ELSE 1 END * (
        Monday + Tuesday + Wednesday + Thursday + Friday + Saturday + Sunday)) AS DaysBooked

FROM
    #UglyTable

GROUP BY
    ResourceName
    , Datepart(m, WeekStarting)
    , Datepart(yyyy, WeekStarting)
