复杂的Oracle查询不会返回正确的信息

下面是问题的一个更直接的部分。以下查询有问题。它返回客户曾经使用过的每个ip_address，而不是过滤当前月份的ip_address。当deallocation_date为空或日期之间是唯一需要选择的IP地址时。这里直接查询的是我试图做一个相关的子查询使用，如果它存在于这些条件计数，总和为这些IP地址。然而，下面我显示，只有29个IP地址deallocation_date = null，并在这些日期之间释放，因为对于该客户，最大释放日期是在8月。我知道它选择了所有分配给客户的IP。请帮我修复子查询以返回正确的数据。我用SQL知道自己的错误在哪里并不是那么棒。我知道这与我使用或使用的方式有关。复杂的Oracle查询不会返回正确的信息

我也知道，因为有人指出，它只会选择直到本月最后一天的00:00:00，现在我确定我可以稍后再解决。我需要它来返回正确的数据。据我所知，这个客户本月没有解除分配。

麻烦的部分是：

和（TRUNC（d.deallocation_date）TO_DATE（间：run_date）和LAST_DAY（：run_date）或f.deallocation_date为null））

因为应该过滤无论ip_address_usages表中的内容为多少，IP的值都为29，但计数停留在57，这意味着它将它们全部选中。

我试图总结从ip_address_usages表发送和收到的字节，同时计数属于之间的客户有空的释放日期的月份的第一天和最后一天的不同ip_address_id的，或该月的第一天和最后一天之间的值。当我运行下面的第一个查询时，它将返回与客户关联的IP地址数量错误。

我明显可以看到它没有考虑本月的最后一天和第一天，但是当我补充说它抛出了总结，如下所示。我正在努力使汇总和IP帐户是正确的。

这里是表格关系，我只列出了相关的描述。

你能否把一个可重复的测试案例（即我们可以在系统中创建你所需要的表，填充一些虚拟的数据，并显示出我们预期的结果运行的东西）？否则，其他人几乎不可能猜测问题出在哪里。 – 2014-10-27 23:01:24

的LAST_DAY函数返回的日期该月的最后一天作为输入提供，但它也包括你提供的日期的时间部分，所以你的第

d.deallocation_date between to_date(:run_date) and last_day(:run_date))

大概应该是

truncate(d.deallocation_date) between to_date(:run_date) and last_day(:run_date))

您的代码集：run_date为varchar场没有时间组件，所以LAST_DAY（：run_date）将是00:00:00，所以如果d.deallocation_date有时间晚于此时，它不会被选中。

我看到，但有什么毛病我的查询，它实际上不是过滤释放日期它只是不断选择所有 – 2014-10-27 23:58:46

能否请你看问题的顶部，现在，只是帮助我的子查询@马克·斯图尔特 – 2014-10-28 00:05:46

啊，好的，对不起，@Grant。我现在也很难过！ – 2014-10-28 00:18:48

至于这一部分：

(trunc(d.deallocation_date) between to_date(:run_date) and last_day(:run_date) 
or f.deallocation_date is null))

如果您要在or两侧使用deallocation_date来自同一个表？
