[jira] [Created] (CALCITE-1306) Allow GROUP BY and HAVING to
reference SELECT expressions by ordinal and alias

------------------------------------
Summary: Allow GROUP BY and HAVING to reference SELECT expressions by ordinal and alias
Key: CALCITE-1306
URL: https://issues.apache.org/jira/browse/CALCITE-1306
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Allow GROUP BY and HAVING to reference SELECT expressions by ordinal and alias. It is not standard SQL, but MySQL and PostgreSQL allow it.
See [http://stackoverflow.com/questions/3841295/sql-using-alias-in-group-by|Stack Overflow: SQL - using alias in Group By] .
It would be enabled only by new methods {{isGroupByOrdinal}} and {{isGroupByAlias}} in SqlConformance.
We might allow alias in the HAVING clause (as described in HIVE-10557) but ordinal does not make sense.
