【问题描述】：

我正在使用此查询来获取每位员工两周的总工资期。

select FullName
,[Sunday] = SUM([Sunday])
,[Monday] = SUM([Monday])
,[Tuesday] = SUM([Tuesday])
,[Wednesday] = SUM([Wednesday])
,[Thursday] = SUM([Thursday])
,[Friday] = SUM([Friday])
,[Saturday] = SUM([Saturday])
, Total=SUM(ISNULL([Sunday],0)+ISNULL([Monday],0)+ISNULL([Tuesday],0)+ISNULL([Wednesday],0)+ISNULL([Thursday],0)+ISNULL([Friday],0)+ISNULL([Saturday],0))
   from  
    (Select UserId_Fk,ISNULL(CAST(CountHours as decimal(18,2)),0)as CountHours,[Day],CheckIn 
    from CheckInCheckOut)
    as convertedtable
    inner join Users
    on convertedtable.UserId_Fk=Users.UserId
 PIVOT
(
 SUM(CountHours) 
 FOR Day
 IN([Sunday],[Monday],[Tuesday],[Wednesday],[Thursday],[Friday],[Saturday])
)
as PivotTable where CheckIn between @startdate and @enddate 
GROUP BY FullName
end

输出是这样的：

如何更新我的查询以将其显示为：

 Monday Tuesday Wednesday Thursday Friday Saturday Sunday Monday Tuesday Wednesday Tursday Friday Saturday **Total**

数据库中的数据是：

编辑我有一个名为 Paperiod 的表格，其中列出了当年的所有支付期：

表格的第一行是：

    Monday  21 Apr 2014 - 4 May 2014

示例将不胜感激。

【问题讨论】：

第一个星期日是哪个星期日？一个支付期是从 2014-05-04 到 2014-05-17，还是从 2014-05-11 到 2014-05-24？
我很好奇您是如何填充 Day 列的。例如，第一行中的所有日期均指 2014-05-15，即星期四，但 Day 列有星期三。您的查询是否基于 Day 列的内容？还是基于日期字段之一？
@DavidDubois 请查看更新。我带来了当天的数据。
你不能有两次相同的别名，你必须在表示层解决这个问题

【解决方案1】：

从计算从支付期开始到员工工作之日的天数的查询开始。

select *, 
  DateDiff(day, @start_date, Day_Worked) as Day_Of_Period 
  from WorkHours

在本例中，新字段 Day_Of_Period 将是从 0 到 13 的数字。

然后根据该新字段生成数据透视表。

我尝试了你的实现，但没有成功。我知道我可以按照你的建议去做...你能告诉我如何将你的实现集成到我的查询中吗？
