I have an question regarding the index type of
a primary key.  I have to store object instances ids,
each instance has a 128 bit GUID as a primary
key/foreign key for mutiple tables.  These will
be a very large tables so performance is critical.



For performance reasons, is it better to have a
primary key of VARCHAR(32) or NUMBER(28)?



Any ideas or insights?



TIA.  Brian
