-------------------------------------
> JPQL extension: scalar functions in GROUP BY
> --------------------------------------------
>
> Key: OPENJPA-491
> URL: https://issues.apache.org/jira/browse/OPENJPA-491
> Project: OpenJPA
> Issue Type: New Feature
> Affects Versions: 0.9.0, 0.9.6, 0.9.7, 1.0.0, 1.0.1
> Reporter: Patrick Linskey
> Fix For: 1.1.0
>
>
> JPQL does not allow scalar functions to be used in GROUP BY clauses. This can be useful. Example:
> select substring(o.stringField, 1, 1), count(o) from AllFieldTypes o
> group by substring(o.stringField, 1, 1)
