My problem is that I have to update a field of an object based on ID field.
There are some eager loaded collections/objects in that object.So, If i load that object either using get/load or using Criteria then it will load all the child objects also.

If I use Projections to have only the column I want, it returns me String but I want the object to be returned somehow so that I can just set its field to updated value and use hibernate’s automatic dirty checking feature.

So, could anybody please let me know how can I achieve that without writing SQL query?

    How about using jpql to update the field?

    e.g.

    like it is done in this example:

        UPDATE Publisher pub SET pub.status = 'outstanding'
    WHERE pub.revenue < 1000000 AND 20 > (SELECT COUNT(mag) FROM pub.magazines mag)
