Oracle 'MEMBER OF' function - oracle11g

Question

I was trying to use MEMBER OF function but receiving error "PLS-00306: wrong number or types
of arguments in call to 'MEMBER OF'.". Please let me know, how i can use 'MEMBER OF' function
correctly, i want to avoid iteration.
Table: Employee
EMP_ID EMP_NAME EMP_BRANCH
1 Oliver 104
2 Harry 105
3 Jack 105
4 Jacob 103
DECLARE
TYPE emp_name_type IS RECORD(emp_name employee.emp_name%type);
TYPE emp_name_table_type IS TABLE OF emp_name_type;
emp_name_table_type_array emp_name_table_type;
BEGIN
select x.emp_name BULK COLLECT
into emp_name_table_type_array
from (
select e.emp_name, min(e.emp_id) as emp_id
from employee e
where e.emp_branch = 105
group by e.emp_name
) x
order by x.emp_id;
-- receiving output Harry + Jack
FOR i IN emp_name_table_type_array.FIRST .. emp_name_table_type_array.LAST LOOP
dbms_output.put_line(emp_name_table_type_array(i).emp_name);
END LOOP;
-- here i want to implement something like bellow using 'Member OF' function
IF 'Harry' MEMBER OF emp_name_table_type_array THEN
dbms_output.put_line('yes');
ELSE
dbms_output.put_line('no');
END IF;
END;

Thank you

Answer 1

You have one type declaration too many (and have to fix the first dbms_output.put_line call because of that).
