/**

 * This method is strictly a workaround utility method for an issue with using

 * generates an sql statement correctly but binds the parameters wrong. This issue has
 * been reported SEVERAL times, as early as 05 and it still hasn't been fixed (it's
 * 09). There is a 2 second correction that needs to be added to the code to fix the
 * issue but for some reason Hibernate developers refuse to do it. In light of not
 * knowing what else it might break in custom compiling Hibernate with the fix it was
 * preferred to do a work around. It is to be used directly with
