I am new at this, I am trying to view a geocode script to look in db1 from db2. I am using the:

select sdo_gcdr.geocode('NAVTEQ_SF', sdo_keywordarray('33 Montgomery St.', 'San Fransisco, CA 94104'), 'US', 'Default') from dual;

i think this is right...

How can i call the schema and there tables from another database?
