Is there a query to get a list of projects that haven't had any data written to Project Tracker artifacts?

This script will show empty projects:

select MODULE_ID from SCARAB_ISSUE 
    left outer join SCARAB_TRANSACTION on 
    (TRANSACTION_ID = MODIFIED_TRANS_ID 
    AND CREATED_DATE > '20061120130400') 
    WHERE TRANSACTION_ID IS NULL AND MODULE_ID != 1;
