OUTPUT parameter in procedures

Question

Hi all,
What is the difference between OUT parameter in proc1 and porc2?
When I'm moving values to the output parameter from temp table, how it should be?
         OPEN result FOR
       SELECT emp_id empl_id_set
         FROM emp_table
create or replace proc1
p_id IN NUMBER,
"result OUT SYS_REFCURSOR"
create or replace proc2
p_id IN NUMBER,
"result OUT emp_table%ROWTYPE"
)Thanks,

Answer 1

Thank you so much.
Your answer really useful.
As I'm really new to PL/SQL programming,I got some more doubts from ur answer.
Please have a look at my below procedure (Some of forum people already femiliar with the proc :) .....still I'm struggling to solve this question. )
I pass the result to .NET.
PROCEDURE get_sitename_and_dir_lanes
     in_report_parameter_id   IN      report_tasks.report_task_id%TYPE,
     result_site_name         OUT     SYS_REFCURSOR,
     result                   OUT     SYS_REFCURSOR
AS
    CURSOR lane_numbers(c_site_id NUMBER, c_direction_id NUMBER) IS
       SELECT site_lane_id
      FROM site_lanes
         JOIN report_parameters
           ON site_lane_id = report_parameter_value
        WHERE site_lanes.site_id           = c_site_id
          AND site_lanes.site_direction_id = c_direction_id
          AND report_parameters.report_parameter_id  = in_report_parameter_id
          AND report_parameters.report_parameter_group = 'LANE'
       AND report_parameters.report_parameter_name  = 'LANE'
  ORDER BY site_lane_id;
     CURSOR direction_id IS
     SELECT site_direction_id
       FROM site_direction
       JOIN sites
         ON site_direction.site_id = sites.site_id
       JOIN report_parameters
         ON site_direction.site_id = report_parameter_value
      WHERE report_parameters.report_parameter_id  = in_report_parameter_id
           AND report_parameters.report_parameter_group = 'SITE'
        AND report_parameters.report_parameter_name  = 'SITE_ID'
   ORDER BY site_direction_id; 
  my_site_id sites.site_id%TYPE;      
  my_lane_numbers_string VARCHAR(100);
  my_site_name sites.short_name%TYPE;
  lane_numbers_d VARCHAR(200);
BEGIN
  my_site_id := edr_rpt_get_site_id(in_report_parameter_id);
  SELECT short_name
     INTO my_site_name
     FROM sites
     WHERE site_id = my_site_id;
  my_lane_numbers_string := '';
  FOR direction_id_row IN direction_id
  LOOP
         IF LENGTH(my_lane_numbers_string) > 0 THEN
            my_lane_numbers_string := my_lane_numbers_string || ',';
         END IF;
      FOR my_lane_number IN lane_numbers(my_site_id,direction_id_row.site_direction_id)
      LOOP
               my_lane_numbers_string := my_lane_numbers_string || my_lane_number.site_lane_id;
               insert into tmp_lanes_table values (my_lane_numbers_string);
       END LOOP;
  END LOOP; 
      open result_site_name for
      select my_site_name site_name
      from sys.dual;
         OPEN result FOR
       SELECT lane_id lane_numbers_d
         FROM tmp_lanes_table;
END get_site_and_dir_lanes;During runtime, I got error as
PLS-00306: wrong number or types of arguments in call to 'GET_SITENAME_AND_DIR_LANES'When I had look for this error, I found one answer from previous post as , I need to do some change in OUT paramter.
Even from the good answers, I cant figure out what to do. I want multiple rows of record should get move to .NET(1.I want all lane id's in each directions should get move to .NET ,and 2.Site name ). Is my procedure is good one?
You told about single row.Please clear me.
If you ahev a look at procedure, you could suggest me
