You would need to do two select. First to find out what is in c1 and is not in c2 and the other way around. An example is below. Note: you need to compare each column.
SELECT * from c1 ;
 WHERE c1.field1 <> c2.field2 AND ;
       c1.field2 <> c2.field2 AND ;
INTO CURSOR
Al alternative if what you really wanted was the two tables merged without any duplicates would be to UNION them together then do a GROUP BY on every field in the table. The result is all records from both tables without duplicates.
