Yury Gerzhedovich updated IGNITE-14885:
---------------------------------------
Labels: calcite2-required calcite3-required (was: )
> Calcite engine. Allow grouping by alias or ordinal
> --------------------------------------------------
>
> Key: IGNITE-14885
> URL: https://issues.apache.org/jira/browse/IGNITE-14885
> Project: Ignite
> Issue Type: Improvement
> Reporter: Aleksey Plekhanov
> Priority: Major
> Labels: calcite2-required, calcite3-required
>
> Currently, grouping by alias or ordinal is not supported, but sometimes it
> can be handy.
> Some DB vendors support this feature (PostgreSQL, MySQL), but some not
> (Oracle, MSSQL). In the current Ignite H2-based SQL engine, this feature is
> not supported. We should decide do we need it in Ignite with calcite-based
> SQL engine.
> This feature can be easily enabled by redefining
> {{SqlConformance#isGroupByAlias}}, {{SqlConformance#isGroupByOrdinal}}
> Affected tests:
> {{src/test/sql/aggregate/group/test_group_by.test}}
> {{src/test/sql/aggregate/group/test_group_by_alias.test}}
> And many other.
