Question

我正在努力展示前一周没有进入任何时间的员工。我目前正在使用三张桌子。一个表是具有每周第一个日期的日历。周格式为周日至周六。第二个表是输入的小时列表。时间表包含输入时间的日期和员工姓名。第三个表是所有员工的列表。我似乎无法让联接工作，我希望他们如何。最终结果我想看到Bob在第7周和第8周输入时间，但第9周为空。谢谢您的帮助。非常感谢。

当前代码

SELECT
    d.Resource
    ,SUM(p.Hours) AS Hours
    ,m.[WeeksSundayToSaturday]
    ,DatePart(wk, m.[WeeksSundayToSaturday]) AS WeekNumber

FROM CalendarWeeks m

LEFT JOIN [TimeTracking] p ON 
(m.[WeeksSundayToSaturday] BETWEEN p.Date AND p.Date + 7)

RIGHT JOIN [DepartmentMembers] d ON
d.Resource = p.CreatedBy 


GROUP BY
d.Resource
,m.WeeksSundayToSaturday

选择       d.Resource       ，SUM（p.Hours）AS Hours       ，米。[WeeksSundayToSaturday]       ，DatePart（周，周[周刊周刊]）AS周数

FROM CalendarWeeks m

LEFT JOIN [TimeTracking] p ON（p.Date BETWEEN   m。[WeeksSundayToSaturday]和Dateadd（d，6，m。[WeeksSundayToSaturday]）

RIGHT JOIN [DepartmentMembers] d ON d.Resource = p.CreatedBy

GROUP BY d.Resource，m.WeeksSundayToSaturday
