问题描述

以下是我的查询:

Quote:

选择a.Sent,b.Recd,((b .Recd-a.Sent)* 1440)DIFF

来自TableA b,TableB a

其中b.type =''AAA''

和b.ID = a.ID1





其中ID和ID1是外键

两者都发送,Recd日期是格式如''

Quote:

5/9/2011 5:22:00 PM

''



但我没有得到:

Quote:

((b.Recd-a.Sent)* 1440 )

在几分钟内

相反,我得像

Quote:

-000000000 06:48:00







我只需要在几分钟内完成DATE的差异。



请建议。

解决方案

  SELECT  
截断(DATE1-DATE2)天,
mod (trunc((DATE1-DATE2)* 24 ), 24 )HOURS,
mod (trunc((DATE1-DATE2)* 1440 ), 60 )MINUTES,
mod (trunc((DATE1-DATE2)* < span class =code-digit> 86400 ), 60 )SECONDS
FROM dual;



根据您的表格更改

这应该这样做:

 选择 
round((second_date - first_date)* < span class =code-digit> 1440 , 2

您需要对值进行舍入。


我建​​议您尝试使用 NUMTODSINTERVAL [< a href =http://docs.oracle.com/cd/B28359_01/server.111/b28286/functions108.htmtarget =_ blanktitle =新窗口> ^ ]功能与第二个''MINUTE''的参数。



 NUMTODSINTERVAL(b.recd  -  a.sent,''MINUTE'')


Below is my Query :

Quote:

Select a.Sent, b.Recd, ((b.Recd-a.Sent)*1440) DIFF
from TableA b, TableB a
where b.type = ''AAA''
and b.ID = a.ID1



Where ID and ID1 are foreign Key
Both sent, Recd dates are in format like ''

Quote:

5/9/2011 5:22:00 PM

''

But i am not getting :

Quote:

((b.Recd-a.Sent)*1440)

in minutes
Instead i am getting like

Quote:

-000000000 06:48:00




I need the difference of DATE in Minutes only.

Please suggest.

解决方案

SELECT
trunc(DATE1-DATE2) days,
mod( trunc( ( DATE1-DATE2 ) * 24 ), 24) HOURS,
mod( trunc( ( DATE1-DATE2 ) * 1440 ), 60 ) MINUTES,
mod( trunc( ( DATE1-DATE2 ) * 86400 ), 60 ) SECONDS
FROM dual;


change as per ur table

This should do it:

select
  round((second_date - first_date) * 1440,2)

You need to round the value.


I suggest that you try using the NUMTODSINTERVAL[^] function with the second parameter of ''MINUTE''.

NUMTODSINTERVAL(b.recd - a.sent, ''MINUTE'')
