> 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.
