This is not supported at the moment, but there are some early
attempts to support it in Cayenne expressions and also JPA
expressions. E.g.:
http://cwiki.apache.org/CAY/expression-functions.html
In other words we need some design discussion to move forward this
effort, either on the dev list, on the wiki, or Jira.

This would be a handy way to avoid having to hard code SQL
statements or manually looping through loaded entities in a context
to achieve the same thing. Obvious applications such as adding up
invoice lines where speed and clarity are very important.
If this doesn't exist should I create a Jira task for it?
