James Starr updated CALCITE-4172:
---------------------------------
Summary: SqlValidatorImpl.validateGroupClause should expand identifiers
before resolving them against the catalog (was:
SqlValidatorImpl.validateGroupClause attempts to resolve parts of the group by
clause before expanding)
> SqlValidatorImpl.validateGroupClause should expand identifiers before
> resolving them against the catalog
> --------------------------------------------------------------------------------------------------------

> Key: CALCITE-4172
> URL: https://issues.apache.org/jira/browse/CALCITE-4172
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: James Starr
> Priority: Major
>
> I am attempt to support a Linq style syntax where you can 'dot' into a
> complex element. In order to do this I am attempt to use
> SqlValidatorImpl.expand and related functions to rewrite the columnar
> identifiers before they are validated.
> SqlValidatorImpl.validateGroupClause calls SqlValidatorImpl.inferUnknownTypes
> which attempts to resolve the identifiers against the catalog. Every where
> else that I am aware of first expands the identifier if configured to before
> resolving.
> SqlValidatorImpl.validateGroupClause immediately after calling
> inferUnknownTypes expands the identifiers.
