How to match three letter month name in Hive queries

[Thimuth Amarakoon <th...@gmail.com>]

Hi,

How can we match a date value like *2014-Dec-20* in unix_timestamp()? The
pattern *yyyy-MM-dd* matches 2014-12-20 format. But yyyy-mmm-dd or
yyyy-m-dd is not doing the trick for matching the month name.

Thanks and regards,
Thimuth

Hi Thimut,

I believe that the UDF unix_timestamp uses the java class SimpleDateFormat.
http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

>From the doc, you can see that "m" denotes a minute while "M" denotes a
month.
For your problem, "yyyy-MMM-dd" should do the trick.
