我有簡單的表員工id，開始年份，結束年份。我必須找出有多少員工在最低年份工作。如果分年是2000年和最大。應該列出所有這些年份從2000年到2017年的工作僱員人數每年有多少員工工作？

我正在考慮更多的動態SQL。請參閱上面的示例表和註釋。除此之外，我非常感謝您的幫助！ – HankerPL

NOT_ACTIVE暗示什麼？它是否會影響報告查詢？有許多重複的行像第2行和第4行。如果相同的USER_ID在特定年份中有多個條目，那麼您是否將它們作爲單獨的或相同的添加？ – Slkrasnodar

在這種情況下，我們只需要爲特定的user_id選擇ACTIVE GROUP條目，並從VALID_FROM和max中選擇最小值。 VALID_TO的值來檢查某個員工在公司工作的時間（時間範圍）。除此之外，我們通過從DATE中提取年份（VALID_FROM，VALID_TO＆SYSDATE作爲實際年份=在這種情況下，我假定提取（年份從SYSDATE）應該被處理爲最大年份2017 =最大值而不是9999） MAX;） – HankerPL
