Attachment: openjpa.patch
> Add support for calculating update value in QueryImpl.updateInMemory

>
> 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.
