> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Timo Walther
>
> Calcite supports many SQL functions by translating them into {{RexNode}} s.
> However, SQL functions like {{NULLIF}}, {{OVERLAPS}} are neither tested nor
> document although supported.
> These functions should be tested and added to the documentation. We could
> adopt parts from the Calcite documentation.
