Justin,

This is from the spec.


         primaryCatalog - a catalog name; "" retrieves those without a
         catalog; null means drop catalog name from the selection
         criteria
         primarySchema - a schema name; "" retrieves those without a
         schema
         primaryTable - the table name that exports the key
         foreignCatalog - a catalog name; "" retrieves those without a
         catalog; null means drop catalog name from the selection
         criteria
         foreignSchema - a schema name; "" retrieves those without a
         schema
         foreignTable - the table name that imports the key


         No where do I see primary table can be null, or foreign table
         can be null and what cross reference would there be if
         primary=foreign?

         Dave
