使用Netezza以秒为单位的时差? [英] Time Difference in Seconds using Netezza?

问题描述

我想在秒钟内在Netezza中获得以分钟为单位的时差.

I want to Get time difference in minutes in Netezza in Seconds.

我有2列:Start(2014-06-01 07:45:04)和finish(2014-06-01 07:46:58)事件

我尝试使用DATEDIFF(SECOND,start,finish)，但是Netezza出现错误.

I have tried Using DATEDIFF(SECOND,start,finish), but Netezza shoots an error.

我缺少一个功能吗?

Select R.*,S.*,CM.URL,DATEDIFF(SECOND,R.EVENT_DTM,S.MIN) From CTE_1 R 
JOIN CTE_2 S
on S.VISIT_KEY = R.VISIT_KEY
JOIN ADMIN.VW_DIM_CME_METADATA CM on CM.CONTENT_METADATA_KEY = R.CONTENT_METADATA_KEY

推荐答案

在IBM论坛上进行了一些搜索，发现这可行.如果有人提供更好的方法，请发布.谢谢

Did some Searching on the IBM forums and found this which works. If someone comes with better way please do post it. Thanks

    Select 
    R.*,S.*,CM.URL,
    EXTRACT(EPOCH from S.MIN - R.EVENT_DTM)DIFF 
    From CTE_1 R 
    JOIN CTE_2 S
    on S.VISIT_KEY = R.VISIT_KEY
    JOIN ADMIN.VW_DIM_CME_METADATA CM on CM.CONTENT_METADATA_KEY = R.CONTENT_METADATA_KEY
