Creation Date - Date format dd/mm/yyyy hh24:mi:ss
Oldest cdr date - Date format dd/mm/yyyy hh24:mi:ss
如何计算Oracle SQL中两个日期之间的小时分钟和秒（以及可能的天数）的差异？
由于
答案 0 :(得分：108)
您可以在Oracle中减去日期。这将给你几天的差异。乘以24得到小时，依此类推。
SQL> select oldest - creation from my_table;
如果您的日期存储为字符数据，则必须先将其转换为日期类型。
SQL> select 24 * (to_date('2009-07-07 22:00', 'YYYY-MM-DD hh24:mi')
- to_date('2009-07-07 19:30', 'YYYY-MM-DD hh24:mi')) diff_hours
from dual;
DIFF_HOURS
----------
2.5
注意：
此答案适用于Oracle数据类型DATE表示的日期。
Oracle还有一个数据类型TIMESTAMP，它也可以表示日期（随时间）。如果您减去TIMESTAMP个值，则得到INTERVAL;要提取数值，请使用EXTRACT函数。

select
extract( day from diff ) Days,
extract( hour from diff ) Hours,
extract( minute from diff ) Minutes
from (
select (CAST(creationdate as timestamp) - CAST(oldcreationdate as timestamp)) diff
from [TableName]
);
这将为您提供三列，分别为天，小时和分钟。
答案 4 :(得分：6)
您可以使用to_timestamp函数将日期转换为时间戳并执行子操作。
类似的东西：
SELECT
TO_TIMESTAMP ('13.10.1990 00:00:00','DD.MM.YYYY HH24:MI:SS') -
TO_TIMESTAMP ('01.01.1990:00:10:00','DD.MM.YYYY:HH24:MI:SS')
FROM DUAL
答案 5 :(得分：5)
你也可以试试这个：
select to_char(to_date('1970-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')+(end_date - start_date),'hh24:mi:ss')
as run_time from some_table;
它以更易读的形式显示时间，如：00：01：34。 如果您还需要几天，您可以简单地将DD添加到最后的格式化字符串。

如果您想要看起来更简单的东西，请尝试使用此方法查找过去1分钟内发生的表格中的事件：
使用此条目，您可以调整小数值，直到获得所需的分钟值。就sysdate有效数字而言，值.0007恰好是1分钟。您可以使用它的倍数来获得您想要的任何其他值：
select (sysdate - (sysdate - .0007)) * 1440 from dual;
结果为1（分钟）
然后检查

如果您从“ your_table ”中选择两个日期，并希望将结果视为单列输出（例如'天 - hh：mm： ss '）你可以使用这样的东西。 首先，您可以计算这两个日期之间的间隔，然后从该区间导出所需的所有数据：
select extract (day from numtodsinterval (second_date
- add_months (created_date,
floor (months_between (second_date,created_date))),
'day'))
|| ' days - '
|| extract (hour from numtodsinterval (second_date
- add_months (created_date,
floor (months_between (second_date,created_date))),
'day'))
|| ':'
|| extract (minute from numtodsinterval (second_date
- add_months (created_date,
floor (months_between (second_date, created_date))),
'day'))
|| ':'
|| extract (second from numtodsinterval (second_date
- add_months (created_date,
floor (months_between (second_date, created_date))),
