PL/SQl sqldeveloper want to output multiple rows in plsql

Question

I have a procedure and anonymous block, where I enter in two dates and it searches the tickets table for the tickets that have been resolved during those two dates and outputs em. But I can't seem to figure out how to output multiple rows in pl/sql.

ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "SYSTEM.JOBS_DONE", line 9
ORA-06512: at line 8
01422. 00000 -  "exact fetch returns more than requested number of rows"
*Cause:    The number specified in exact fetch is less than the rows returned.
*Action:   Rewrite the query or change number of rows requested

CREATE OR REPLACE PROCEDURE jobs_done(
  month_start    IN  tickets.date_reported%TYPE,
  month_end      IN  tickets.date_resolved%TYPE,
  userid         OUT tickets.user_id%TYPE,
  supportstaffid OUT tickets.support_staff_id%TYPE,
  resolution     OUT tickets.resolution_details%TYPE)
AS
  BEGIN

    SELECT user_id, support_staff_id, resolution_details
      INTO userid, supportstaffid, resolution 
      FROM tickets
     WHERE date_resolved >= month_start AND date_resolved <= month_end;

    dbms_output.put_line('userid, supportstaffid, resolution');
    dbms_output.put_line(userid || supportstaffid || resolution);

  END jobs_done;
/

SET serveroutput ON

DECLARE
  month_start    tickets.date_reported%TYPE := &Enter_date_start;
  month_end      tickets.date_resolved%TYPE := &Enter_date_end;
  userid         tickets.user_id%TYPE;
  supportstaffid tickets.support_staff_id%TYPE;
  resolution     tickets.resolution_details%TYPE;
BEGIN
  jobs_done(month_start, month_end, userid, supportstaffid, resolution);
END;
/

Based on new information: your query returns multiple records. With this type of select you can only fetch one row. Try using a cursor. e.g. structure like this:

declare
  cursor c1 is <select your thing from table>;
begin
 for r1 in c1
loop
  dbms_output.put_line (r1.firstcolumn|| r2.anothercolumn );
end loop;
end;

I dont think thats the problem im getting the error : RA-01422: exact fetch returns more than requested number of rows ORA-06512: at "SYSTEM.JOBS_DONE", line 9 ORA-06512: at line 8 01422. 00000 - "exact fetch returns more than requested number of rows" *Cause: The number specified in exact fetch is less than the rows returned. *Action: Rewrite the query or change number of rows requested – itadaki Dec 01 '15 at 13:26
right. that means your code doesn't get to the point where the dbms_output is executed. – Non Plus Ultra Dec 01 '15 at 13:31

The problem is that will not work like that. If your objectif is to see the output, you must iterate on the list of results. What you wrote has no meaning to PL/SQL block. You must create a cursor that keeps the results and iterate into it.

CREATE OR REPLACE PROCEDURE jobs_done(
month_start IN tickets.DATE_REPORTED%TYPE,
month_end IN tickets.DATE_RESOLVED%TYPE,
userid OUT TICKETS.USER_ID%type,
supportstaffid OUT tickets.support_staff_id%type,
resolution OUT tickets.resolution_details%type)
AS
Begin
  DECLARE
  CURSOR V_CURS IS
  select user_id, support_staff_id, resolution_details 
  where DATE_RESOLVED >= month_start AND DATE_RESOLVED <= month_end;
  BEGIN
      DBMS_OUTPUT.PUT_LINE('userid, supportstaffid, resolution');
      FOR V_CURS_RES IN V_CURS LOOP
       DBMS_OUTPUT.PUT_LINE(V_CURS_RES.userid || V_CURS_RES.supportstaffid || V_CURS_RES.resolution);   
      END LOOP;
  END;      


END jobs_done;

set serveroutput on
DECLARE
  month_start tickets.DATE_REPORTED%TYPE := &Enter_date_start;
  month_end tickets.DATE_RESOLVED%TYPE := &Enter_date_end;
  userid TICKETS.USER_ID%type;
  supportstaffid tickets.support_staff_id%type;
  resolution tickets.resolution_details%type;
BEGIN
  jobs_done(month_start, month_end, userid, supportstaffid, resolution);
End;

    Try this. Returning refcursor is the best way for this kind of resultset.

    CREATE OR REPLACE PROCEDURE jobs_done(
    month_start IN tickets.DATE_REPORTED%TYPE,
    month_end IN tickets.DATE_RESOLVED%TYPE,
    cur_out OUT sys_refcursor
    )
     AS
     OPEN cur_out FOR
     select user_id, support_staff_id, resolution_details 
     from tickets where DATE_RESOLVED >= month_start AND DATE_RESOLVED <= month_end;
     END jobs_done;

var ls refcursor;
EXEC jobs_done(input1,input2,:ls);
print ls;
