    View geocoding from another database

    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?

    the way to query tables on database "B" when you are sitting on database "A" is by creating a DBLink on database "A" pointing to database "B".

    would it look like this?

    CREATE PUBLIC DATABASE LINK db1
    USING 'db1_link';

    on db2:

    select * from user_tables@db1; is this correct?

    If so, how does this work with clobs? how do you see the clob's or blob's from db1 an db2?

    *Which the db1_link is the tnsname set up for the db1_link, correct?

    2- you cannot directly access LOBs over a DBLink.
