在日期之間進行過濾Oracle SQL Developer

Question

我正在運行此查詢以查看兩個日期之間的數據，如下面的代碼所示，但是我僅獲取當前日期（如果日期是連續的）或日期間隔前一天的數據。

我的意思是：

• 如果間隔（16/05/18-17/05/18）僅返回16/05/18的數據。

• 如果interval為（16/05/18-18/05/18）僅返回interval（16/05/18-17/05/18）的數據

碼：

Answer 1

您正在將列值與字符串值進行比較，這意味着Oracle使用會話NLS設置將字符串隱式轉換為日期或時間戳。 您可以從執行計划的篩選步驟中看到：

   1 - filter("C"."CALLTIMESTAMP">=TO_TIMESTAMP('16/05/18') AND 
              "C"."CALLTIMESTAMP"<=TO_TIMESTAMP('17/05/18'))

這些隱式轉換的值將時間分量設置為午夜。 （它們也非常脆弱，因為它們依賴於您使用的與會話設置匹配的字符串，但這並不總是在您的控制之下）。

這意味着您正在尋找2018-05-16 00:00:00到2018-05-17 00:00:00之間的值。 這將在16號的一天中的任何時間捕獲值，但只會在17號的恰好午夜找到記錄。

通常的做法是將范圍設置為大於或等於開始日期，並且小於結束日期后的第二天-這意味着您可以捕捉到直到該日的所有但不包括午夜的時間。

AND C.CALLTIMESTAMP >= timestamp '2018-05-16 00:00:00'
AND C.CALLTIMESTAMP < timestamp '2018-05-18 00:00:00'

它將在16日或17日的任何時間查找所有記錄。

如果該列實際上是日期而不是時間戳，則可以改用日期文字：

AND C.CALLTIMESTAMP >= date '2018-05-16'
AND C.CALLTIMESTAMP < date '2018-05-18';

如果您不想使用文字，則可以使用to_date()或to_timestamp() ，使用合適的顯式格式掩碼。 我建議您還是使用完整的四位數年份，而不是兩位數，這仍然會引起混淆（特別是在隱式轉換的情況下，但也容易顯式地出錯...）

Answer 2

我建議您在句子C.CALLTIMESTAMP之間使用'16 / 05/18'和'17 / 05/18'之間的句子；

希望對您有幫助。

謝謝大家，我走了簡單的路
