SQL Query: How to pass list of values to the IN operator

Question

Hi,
I'm trying to pass a list of values to the WHERE <a> IN <list>
I dont want to use dynamic cursors (REF CURSOR). Is this possible using Oracle SQL?
Please let me know.
My program:
DECLARE
list_of_ids := '10, 20, 30';
SELECT MAX(sal) INTO max_sal FROM employee WHERE emp_id IN (list_of_ids);
END;
Thanks in Advance,
Niko

Answer 1

You do not want to pass a comma separated list. You want to pass a collection. So
CREATE TYPE num_tbl
AS
TABLE OF NUMBER;
DECLARE
  l_list_of_ids num_tbl := num_tbl( 10, 20, 30 );
BEGIN
  SELECT max(sal)
    INTO max_sal
    FROM employee
   WHERE emp_id IN (SELECT * FROM TABLE( l_list_of_ids ));
END;
