Question

我正在运行此查询以查看两个日期之间的数据，如下面的代码所示，但我只获取当前日期的数据（如果日期是连续的）或前一天的数据，如果有一个日期间隔。

我的意思是：

如果间隔（16/05/18 - 17/05/18）仅返回16/05/18的数据。
如果间隔为（16/05/18 - 18/05/18），则仅返回间隔数据（16/05/18 - 17/05/18）

代码：

    C.SESSIONID,
    SUBSTR(C.ORIGINATINGNUMBER, INSTR(C.ORIGINATINGNUMBER, ':') + 1,
           INSTR(C.ORIGINATINGNUMBER, '@') - INSTR(C.ORIGINATINGNUMBER, ':') - 1) AS Origen,

Answer 1

您正在将列值与字符串值进行比较，这意味着Oracle使用会话NLS设置将字符串隐式转换为日期或时间戳。您可以从执行计划的过滤步骤中看到：

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

这些隐式转换的值将时间组件设置为午夜。（它们也非常脆弱，因为它们依赖于您使用的匹配会话设置的字符串，并不总是在您的控制之下。）

这意味着您正在寻找2018-05-16 00:00:00和2018-05-17 00:00:00之间的值。这将在16日的任何时间捕获值，但只会在17日找到正好在午夜的记录。

执行此操作的常用方法是使用大于或等于开始日期的范围，小于结束日期之后的日期 - 这意味着您抓住了每一天，但不包括当天的午夜。

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

可以在16日或17日随时查找所有记录。

如果列实际上是日期而不是时间戳，那么您可以改为使用日期文字：

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

如果您不想使用文字，可以使用to_date()或to_timestamp()，使用合适的显式格式掩码。我建议你使用完整的四位数年份，而不是2位数，这仍然会引起混淆（特别是隐式转换，但也很容易明白错误......）

Answer 2

我建议您使用BETWEEN句子 C.CALLTIMESTAMP BETWEEN＆＃39; 16/05/18＆＃39;和＆＃39; 17/05/18＆＃39;;

我希望能帮到你。

谢谢大家，我采取了轻松的方式
