> Decorrelator may produce different column names
> -----------------------------------------------
>
> Key: CALCITE-7058
> URL: https://issues.apache.org/jira/browse/CALCITE-7058
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.40.0
> Reporter: Mihai Budiu
> Assignee: Mihai Budiu
> Priority: Minor
> Fix For: 1.41.0
>
>
> In [CALCITE-7024] I have introduced an assertion (Litmus) check in the
> decorrelator that the output relation type is identical to the input relation
> type. This assertion is too strong, because the decorrelator sometimes
> produces different column names in the result.
> This may be a bug, but in the meantime it can be side-stepped by making the
> check a bit weaker: the types are identical up to column names.
