rowids in 8i are an opaque data-type. so you need to convert
them to something human-readable 1st (btw the column is
called rowid and not rid).
select ROWIDTOCHAR(rowid), name from test;
ROWID NAME

AAAGBFAAIAAAB/tAAA müller
update test set name = 'hallo' where ROWID ='AAAGBFAAIAAAB/tAAA';

no - in oracle sql the colon indicate that you are using a
