Add support for calculating update value in QueryImpl.updateInMemory
--------------------------------------------------------------------
Key: OPENJPA-612
URL: https://issues.apache.org/jira/browse/OPENJPA-612
Project: OpenJPA
Issue Type: Bug
Reporter: Fay Wang
Attachments: openjpa.patch
Since Informix does not support update with in/exists subquery in the where
clause, when doing the bulk update against informix, e.g.,
"update DeptBeanAno d set d.budget = (d.budget * ?1 + ?2) where
d.reportsTo.no = ?3"
we encounter the error of "only-update-primitives" during updateInMemory.
The attached patch fixes this problem by beefing up the support for
arithmetic calcuation of the update value for updateInMemory.
