在Oracle SQL中，如何将天数的十进制表示形式转换为小时数和分钟数？

oracle date

在Oracle SQL中，如何将天数的十进制表示形式转换为小时数和分钟数？,oracle,date,Oracle,Date,我正在处理一个Oracle查询，其中一列返回以十进制表示的天数，其中1天=1.0 我有这样的数字： 0.004722222222222222222222222222222222222223 3.12383101851851851851851851851851851851 0.000856481481481481481481481481481481481479 0.002592592592592592592592592592592592592593 0.0010416666666666666666

我正在处理一个Oracle查询，其中一列返回以十进制表示的天数，其中1天=1.0

我有这样的数字：

0.004722222222222222222222222222222222222223
3.12383101851851851851851851851851851851
0.000856481481481481481481481481481481481479
0.002592592592592592592592592592592592592593
0.001041666666666666666666666666666666666667

我想知道它们各自代表的小时数和分钟数。比如16小时5分钟或者8小时59分钟

我该怎么做？最好是作为字符串返回的单列

您可以将小数转换为间隔，然后提取所需的元素：

WITH data (value) AS (
    SELECT 0.004722222222222222222222222222222222222223 FROM DUAL UNION ALL
