Nie jestem pewien, czy to naprawdę pomaga, czy uważasz, że jest bardziej eleganckie:
create type t_test as table of varchar2(1);
/
DECLARE
--TYPE t_test IS TABLE OF VARCHAR2(1);
v_test t_test;
function get_index(q in t_test, c in varchar2) return number is
ind number;
begin
select min(rn) into ind from (
select column_value cv, rownum rn
from table(q)
)
where cv = c;
return ind;
end get_index;
BEGIN
v_test := NEW t_test('A', 'B', 'A');
dbms_output.put_line( 'A: ' || get_index( v_test, 'A' ) );
dbms_output.put_line( 'B: ' || get_index( v_test, 'B' ) );
dbms_output.put_line( 'C: ' || get_index( v_test, 'C' ) );
END;
/

drop type t_test;
