Question

SELECT SUM(HOURS_WORKED) * 24 as TOTAL_HOURS
FROM(
SELECT  AL.END_TIME - AL.START_TIME as HOURS_WORKED
from FCXP.APPLIED_LABOR AL
where AL.TASK_CARD_EXECUTION_ID = '8ab4f8884428a1540144c998588a7b2c');

嘿伙计们，我刚才想不起的简单问题 - 这是以小数形式返回TOTAL_HOURS，因此10:30小时将显示为10.50。我该如何改变？谢谢！

Answer 1

也许喜欢这个：

SELECT EXTRACT(HOUR FROM NUMTODSINTERVAL(SUM(HOURS_WORKED), 'HOUR'))||':'
   ||EXTRACT(MINUTE FROM NUMTODSINTERVAL(SUM(HOURS_WORKED), 'HOUR')) AS TOTAL_HOURS
FROM (...

Answer 2

查看以下查询：

SELECT TRUNC(2.75) || 'hrs:' ||
   SUBSTR(numtodsinterval(2.75, 'HOUR'), 15,2) || 'mins:' ||
   SUBSTR(numtodsinterval(2.75, 'HOUR'), 18,2) || 'secs' hoursvalue FROM dual

这将返回如下：

<强> hoursvalue 2小时：45分钟：00secs

你也可以使用下面的查询，它也会返回相同的结果：

SELECT TRUNC(2.75) || 'hrs:' ||
   extract (minute from numtodsinterval(2.75, 'HOUR' )) || 'mins:' ||
   extract (second from numtodsinterval(2.75, 'HOUR')) || 'secs'  hoursval
FROM dual

如何将查询结果作为时间HH：MM返回？
