[GENERAL] how to save primary key constraints

[J.V.]

I need to be able to query for all primary keys and save the table name 
and the name of the primary key field into some structure that I can 
iterate through later.

How would I go about this?  I want to hard code the number of tables and 
be able to iterate through some structure to get the table name and the 
primary key field.

Regards,

J.V.
