> Key: FLINK-4109
> URL: https://issues.apache.org/jira/browse/FLINK-4109
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.1.0
> Reporter: Jark Wu
> Assignee: Jark Wu
> Fix For: 1.1.0
>
>
> The ternary condition operator in Table API is named {{eval}}, for example:
> {{(42 > 5).eval("A", "B")}} leads to "A". IMO, the eval function is not well
> understood. Instead the "?" is a better choice I think, which is used in Java
> for condition operator.
> It will be clearer and more literal understood, e.g.
> {{(42 > 5).?("A", "B")}} or {{(42 > 5) ? ("A", "B")}}
> If it make sense, I will pull a request.
