如何獲取不同生效日期的員工詳細信息？

請看下面的圖片。它基本上是我數據庫的外觀。如何獲取不同生效日期的員工詳細信息？

BI_EMPLOYEE表總是有今天的記錄。雖然它可能在某個以前的日期有效。

例如如圖所示的員工Anna從3月31日加入，直到今天沒有對該員工進行更新。

因此，BI_EMPLOYEE有生效日期= 3月31日2012年

但是，後來可能會有變動對將來的日期的員工現在是知道的。

例如安娜在5月10日從亞洲轉移到我們，等等。所以，從10月開始，她的地區將成爲我們。

因此，我需要一份報告，其中列出了所有員工在每個生效日期的狀態。基本上，所有emplyees所有活動和更新日期。

我們還每天運行一次調度，它會運行所有更新和活動，即從更新和活動表向BI_EMPLOYEE TABLE執行chnages。

因此，截至5月10日，地塊將從亞洲轉向我們。

我也提出了預期結果的圖像。

我們正在使用Oracle數據庫。

請幫助。

enter image description here

我將基本上需要創建一個視圖，這將得到期望的輸出然後可以被查詢任何時間以任何報告。

爲什麼關閉？我一直在嘗試這個很長一段時間沒有運氣:( – ashishjmeshram

不贊同近距離投票 - 我已經遇到過這樣的需求一次或兩次自己。 –

@Jeffrey肯普。嗨。你能解決它嗎？任何對此有何建議？ – ashishjmeshram

首先，較好的數據結構是具有在數據的有效日期和結束日期。通過這種方式，您可以查看在任何給定日期哪個記錄處於活動狀態。

幸運的是，你可以得到的結束日期在Oracle中以下查詢：

select eu.*, 
     (lead(effective_date, 1, '9999-01-01') over (partition by employee_id, column_name 
             order by effective_date)) - 1) as end_date 
from bi_employee_update

這個查詢着眼於接下來的生效日期，使用「鉛」分析功能。然後它減去一天得到當前記錄的結束日期，當前記錄的默認值爲01Jan9999。

使用此查詢，您可以通過使用得到有關任何日期的emmployee信息的條款之間：

select eu.* 
from (select eu.*, 
      (lead(effective_date, 1, '9999-01-01') over (partition by employee_id, column_name 
             order by effective_date)) - 1) as end_date 
     from bi_employee_update 
    ) eu 
where <date> between effective_date and end_date

你能不能從這裏走查詢？

感謝您的回答。對不起，但我不確定我是否完全理解。 :( – ashishjmeshram

我改寫了一些東西......有沒有幫助？ –

對不起，沒有運氣:(還有，我不想通過任何日期查詢，只需獲取所有員工在不同日期的所有數據。 – ashishjmeshram
