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 function > --------------------------------- > > Key: HIVE-15982 > URL: https://issues.apache.org/jira/browse/HIVE-15982 > Project: Hive > Issue Type: Sub-task > Components: SQL > Reporter: Carter Shanklin > Assignee: Sahil Takiar > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
