我想生成一个项目进度报告，其中几乎包括检查给定时间范围内已完成里程碑的百分比。（例如：A 公司今天有 10 个到期里程碑，但只有 8 个标记为已完成，因此它们的进度比计划慢 20%。）

这部分很简单，而且效果很好，但是在生成它之前，我确定项目计划是否获得批准。已批准的项目计划是具有里程碑 1 和 2 = 100 的项目计划。

您可以在下面看到我必须使用的表结构。

ID          Company     Project     Milestone   Date        Completion
170825240   Company A   Project 1   Milestone 1 29.10.12    100
170825311   Company A   Project 1   Milestone 2 29.10.12    0
170825242   Company A   Project 1   Milestone 3 05.11.12    100
170825173   Company A   Project 1   Milestone 4 17.12.12    0
170825104   Company B   Project 1   Milestone 1 29.10.12    100
170825035   Company B   Project 1   Milestone 2 29.10.12    100
170824966   Company B   Project 1   Milestone 3 05.11.12    100
170824897   Company B   Project 1   Milestone 4 17.12.12    0
170824828   Company C   Project 1   Milestone 1 29.10.12    100
170824759   Company C   Project 1   Milestone 2 29.10.12    100
170824690   Company C   Project 1   Milestone 3 05.11.12    0
170824621   Company C   Project 1   Milestone 4 17.12.12    0

在此快照中，项目 1 被批准用于公司 B 和 C。

我面临的问题是如何在单个查询进度中组合仅过滤已批准的计划。我不想手动编写异常，因为我们正在讨论公司和项目的 1600 种组合。

有人知道怎么做吗？

谢谢！！！！

添加两个where条件，每个条件都检查里程碑的完成情况：

from    Milestones m
where   exists
        (
        select  *
        from    Milestones m1
        where   m1.Company = m.Company
                and m1.Project = m.Project
                and m1.Milestone = 'Milestone 1'
                and m1.Completion = 100
        )
        and exists
        (
        select  *
        from    Milestones m2
        where   m2.Company = m.Company
                and m2.Project = m.Project
                and m2.Milestone = 'Milestone 2'
                and m2.Completion = 100
        )

这也可以通过从上一个答案中借用的连接来实现；）

select m.* 
(from    Milestones m
inner join Milesones as m1 
      on m1.Company = m.Company
      and m1.Project = m.Project
      and m1.Milestone = 'Milestone 1'
      and m1.Completion = 100)
inner join Milestones as m2
        on m2.Company = m.Company
                and m2.Project = m.Project
                and m2.Milestone = 'Milestone 2'
                and m2.Completion = 100

编辑应该解决一些 ms 访问问题，但不能老实说访问测试它我没有看到 () 围绕第一次加入的好处
