Subject [jira] [Commented] (HIVE-4662) first_value can't have more than one order by column
Date Fri, 11 Mar 2016 08:05:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15190613#comment-15190613
] 

Jesus Camacho Rodriguez commented on HIVE-4662:
-----------------------------------------------

[~ashutoshc], I have just added them. However, second one (row_number) should be executed
over full partition, right? Thus, finally I added:

{noformat}
select  row_number() over (partition by si, bo order by i, f desc range between unbounded
preceding and unbounded following) from over10k limit 100;
{noformat}

Observe that both ends are unbounded.

> In the current implementation of the first_value function, it's not allowed to have more
than one (1) order by column, as so:
> {quote}
> select distinct 
> first_value(kastr.DEWNKNR) over ( partition by kastr.DEKTRNR order by kastr.DETRADT,
kastr.DEVPDNR )
> from RTAVP_DRKASTR kastr
> ;
> {quote}
> Error given:
> {quote}
> FAILED: SemanticException Range based Window Frame can have only 1 Sort Key
> {quote}
