    There is a dynamic version of the @Where setting, it is the @Filter. See:

    • 19.1. Hibernate filters

    Hibernate has the ability to pre-define filter criteria and attach those filters at both a class level and a collection level. A filter criteria allows you to define a restriction clause similar to the existing "where" attribute available on the class and various collection elements.

    Management of @Filter is a bit more complex, in a nutshell:

    • / @FilterDef is needed to define filter
    • / @Filter must be assigned to class or a set
    • filter must be enabled on a session level, e.g.: session.enableFilter("myFilter").setParameter("myFilterParam", "some-value");

    So, this, while being a bit more complex, provides exactly what we need: dynamic @Where to be turned on/off in run-time
