Assuming table > foo[w,x,y,z], use "update foo set x=1, y=1 where w=old_w, x=old_x, > y=old_y, z=old_z" > Beware, (especially with the "or all that are important" thing) this might allow to become your entity out of sync. Means, your entity is a mixture of different updates which you are not aware of then. Using all properties of the version column (which might be more performant) is the only option to prevent this.
