ONe example where ROWNUM would be really usefull if you do a INSERT INTO ... SELECT FROM ... style statement and you want to generate the primary key for the destination table on the fly. For example you have a contact db with cities for persons. You want to create a lookup table for cities, so you do INSERT INTO cities (id, name) SELECT DISTINCT ????, city FROM person. You see?
