Subject [jira] [Updated] (SPARK-29370) Interval strings without explicit unit markings
Date Tue, 08 Oct 2019 18:14:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-29370?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Maxim Gekk updated SPARK-29370:
-------------------------------
    Description: 
In PostgreSQL, Quantities of days, hours, minutes, and seconds can be specified without explicit
unit markings. For example, '1 12:59:10' is read the same as '1 day 12 hours 59 min 10 sec'.
For example:
{code:java}
maxim=# select interval '1 12:59:10';
    interval    
----------------
 1 day 12:59:10
(1 row)
{code}
It should allow to specify the sign:
{code}
maxim=# SELECT interval '1 +2:03:04' minute to second;
    interval    
----------------
 1 day 02:03:04
maxim=# SELECT interval '1 -2:03:04' minute to second;
    interval     
-----------------
 1 day -02:03:04
{code}
