[jira] [Commented] (SPARK-22456) Add new function dayofweek

    [ https://issues.apache.org/jira/browse/SPARK-22456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16240269#comment-16240269 ] 

Sean Owen commented on SPARK-22456:
-----------------------------------

Does it exist in other SQL dialects? that's the reason most functions like this exist in Spark. Beyond that, these sorts of things should be UDFs.
