複雜的Oracle查詢不會返回正確的信息

下面是問題的一個更直接的部分。以下查詢有問題。它返回客戶曾經使用過的每個ip_address，而不是過濾當前月份的ip_address。當deallocation_date爲空或日期之間是唯一需要選擇的IP地址時。這裏直接查詢的是我試圖做一個相關的子查詢使用，如果它存在於這些條件計數，總和爲這些IP地址。然而，下面我顯示，只有29個IP地址deallocation_date = null，並在這些日期之間釋放，因爲對於該客戶，最大釋放日期是在8月。我知道它選擇了所有分配給客戶的IP。請幫我修復子查詢以返回正確的數據。我用SQL知道自己的錯誤在哪裏並不是那麼棒。我知道這與我使用或使用的方式有關。複雜的Oracle查詢不會返回正確的信息

我也知道，因爲有人指出，它只會選擇直到本月最後一天的00:00:00，現在我確定我可以稍後再解決。我需要它來返回正確的數據。據我所知，這個客戶本月沒有解除分配。

麻煩的部分是：

和（TRUNC（d.deallocation_date）TO_DATE（間：run_date）和LAST_DAY（：run_date）或f.deallocation_date爲null））

因爲應該過濾無論ip_address_usages表中的內容爲多少，IP的值都爲29，但計數停留在57，這意味着它將它們全部選中。

我試圖總結從ip_address_usages表發送和收到的字節，同時計數屬於之間的客戶有空的釋放日期的月份的第一天和最後一天的不同ip_address_id的，或該月的第一天和最後一天之間的值。當我運行下面的第一個查詢時，它將返回與客戶關聯的IP地址數量錯誤。

我明顯可以看到它沒有考慮本月的最後一天和第一天，但是當我補充說它拋出了總結，如下所示。我正在努力使彙總和IP帳戶是正確的。

這裏是表格關係，我只列出了相關的描述。

你能否把一個可重複的測試案例（即我們可以在系統中創建你所需要的表，填充一些虛擬的數據，並顯示出我們預期的結果運行的東西）？否則，其他人幾乎不可能猜測問題出在哪裏。 – 2014-10-27 23:01:24

如果我能抽出時間去做，我會在今晚做。感謝您花時間看看。這就是爲什麼我包括這麼多的數據是希望有人能看到什麼即時通訊沒有看到，或者調整我的查詢。基本上它查看了vm_ip_address_histories表中的所有ip並忽略了釋放日期，但是當我將它設置爲查看它拋出我的使用情況數據時，我預計它會減少一點，因爲它不會將壞IP與客戶相關聯但到目前爲止，我就知道它錯了。\ – 2014-10-27 23:05:34

大概應該是

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

您的代碼集：run_date爲varchar場沒有時間組件，所以LAST_DAY（：run_date）將是00:00:00，所以如果d.deallocation_date有時間晚於此時，它不會被選中。

SQL> variable run_date varchar2(30) 
SQL> exec :run_date := to_date('1-oct-14') 

SQL> select to_char(to_date(:run_date), 'yyyy-mm-dd hh24:mi:ss') as first_of_month, 
2*  to_char(last_day(to_date(:run_date)), 'yyyy-mm-dd hh24:mi:ss') as last_of_month from dual; 

FIRST_OF_MONTH  LAST_OF_MONTH

我看到，但有什麼毛病我的查詢，它實際上不是過濾釋放日期它只是不斷選擇所有 – 2014-10-27 23:58:46

能否請你看問題的頂部，現在，只是幫助我的子查詢@馬克·斯圖爾特 – 2014-10-28 00:05:46

啊，好的，對不起，@Grant。我現在也很難過！ – 2014-10-28 00:18:48

至於這一部分：

(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兩側使用deallocation_date來自同一個表？

嗯，我試圖找到它是否有日期的空間，或者如果釋放日期。 – 2014-10-28 14:47:03

複雜的Oracle查詢不會返回正確的信息
