[Quoted] I'm not a Oracle guru, but I use rowid sometimes and can tell you about it that what I know.

No you don't have to use any sequence.
You can use rowid in query just like identity:
MSSQL - select _at__at_identity, t.* from table t ORACLE - select rowid, t.* from table t
you can do now something like
col1 = :col1,
col2 = :col2
rowid = :old_rowid
Remember that rowid is unique for the given query (it is not like oid in postgresql - unique for any table tuple). So when you finish your transaction and then call SELECT once again then the rowid value will be different.
