> Issue Type: Bug
> Components: SQL
> Affects Versions: 0.11.0
> Reporter: Frans Drijver
>
> 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}
