*
** Using the mappings for qualification is very useful for updating values
** after a select, for instance -- all fields except the one being updated
** can have their qualifiesValues set to YES, making the update much less
** ambiguous. The operator used for qualification is ALWAYS "=".
**
** These methods are used in a specific way by upper level DBKit objects;
** don't use them if you are expecting to use application level objects
** with your binder.
