----------------------------------------------------------------

Output of following query in test results looks incorrect:
{code}
 select distinct first_value(t) over ( partition by si order by i, b ) from over10k limit 100;
{code}

It seems {{distinct}} is dropped. Also, add a test case without distinct.

> 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}
