Q:

Oracle script client that exports query result as UPDATE statement

I use Quest TOAD for Oracle and Quest SQL Navigator for Oracle as my database 
query tools of choice.  
These tools allow me to export the query results grid as INSERT statements.  
For example  
SELECT dummy  
FROM dual;

exports to  
INSERT INTO dual
(DUMMY)
VALUES
('X')
/

Is there an Oracle database query tool that exports query results as UPDATE statements?
For example  
SELECT dummy  
FROM dual;

would export to  
UPDATE dual
SET dummy = 'X'
/
