You already know that ORA-01422 is encountered because there are multiple
sessions initiated by the same userid. Obviously you can not fetch
multiple rows into one single variable in a pl/sql block unless you
define a cursor for the purpose. You can make this view accessible
(readable) by other users via a public synonym and granting select
privileges to certain users.
