[jira] [Updated] (CALCITE-4172)
SqlValidatorImpl.validateGroupClause should expand identifiers before
resolving them against the catalog
[ https://issues.apache.org/jira/browse/CALCITE-4172?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
