just assign them -- it'll happen implicitly..
there is an explicit conversion via:
tkyte_at_8.0> select rowidtochar(rowid) from dual;
ROWIDTOCHAR(ROWID)
tkyte_at_8.0> select chartorowid('AAAACsAABAAAAGiAAA') from dual;
CHARTOROWID('AAAAC
as well. but its like a NUMBER and varchar -- you can just assign them and
they'll convert.
