>                 Key: CALCITE-2183
>                 URL: https://issues.apache.org/jira/browse/CALCITE-2183
>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.15.0
>            Reporter: Alessandro Solimando
>            Assignee: Julian Hyde
>            Priority: Minor
>
> Consider the following query:
> {code:sql}
> select *
> from (values (1, 'a'), (2, 'b'), (3, 'b'), (4, 'c'), (2, 'c')) as t(x, y)
> where x between 3 and 4
> {code}
> When executed, an exception is thrown (the full stack trace is at the end) in 
> _copy_ method in _RelSubset_ class, as the method is not meant to be called.
>  
> This happens (in this particular case) while Calcite is trying to get rid of 
> unused terms (specifically, _trimUnusedFields_ method from 
> _SqlToRelConverted_ class).
> This is problematic as the trace of calls is legitimate, so the method should 
> be executable.
> Complete stack trace documenting the issue:
> {noformat}
