> Allow datastore function as query expression
> --------------------------------------------
>
> Key: OPENJPA-1195
> URL: https://issues.apache.org/jira/browse/OPENJPA-1195
> Project: OpenJPA
> Issue Type: New Feature
> Components: query
> Affects Versions: 2.0.0
> Reporter: Pinaki Poddar
> Assignee: Pinaki Poddar
> Fix For: 2.0.0
>
>
> Create a query expression that uses a datastore function such as MOD(..) or
> MAX(..) in a generic fashion.
> This is required by function() support for CriteriaQuery and adds a generic
> capability for queries so we can query something like
> "select CURRENT_USER(), x.name FROM Person x WHERE LENGTH(x.name)>10 ORDER
> BY LENGTH(x.name)"
> Notice that JPQL Parser may not like the syntax -- but CriteriaQuery will
> allow such possibility.
> Allow the function() to accept 0 or more arguments as expressions.
