Sahil Takiar commented on HIVE-15982:
-------------------------------------
Thanks [~cartershanklin]. I'm basing the implementation largely on
https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions214.htm and
https://my.vertica.com/docs/7.1.x/HTML/Content/Authoring/SQLReferenceManual/Functions/Mathematical/WIDTH_BUCKET.htm
- they both mention support for datetime, interval, timestamp, etc. - is that
something we want to support too?

> Support the width_bucket(wbo, wbb1, wbb2, wbc) which returns an integer
> between 0 and wbc+1 by mapping wbo into the ith equally sized bucket made by
> dividing wbb1 and wbb2 into equally sized regions. If wbo < wbb1, return 1,
> if wbo > wbb2 return wbc+1. Reference: SQL standard section 4.4.
