Oracle Stored Procedure's TYPE IS RECORD for join table columns

Question

Hi there,
I'm trying to use the type is record to setup all my output columns; However, these columns are joined from 2 or more tables. i.e.,
TYPE my_rec IS RECORD (
myColumn1 varchar2(50),
myColumn2 varchar2(20)
where myColumn1 is slected from a join of table1 and table2, and myColumn2 is selected from a join of table2 and table3.
as I tried to exec mySP, I got the error:
wrong number or types of arguments in call to 'mySP'
I know it is not "wrong number of arguments", but I don't know why these columns are wrong types? though I had TO_CHAR the new myColumn1 and myColumn2, I'm wondering if I should use %TYPE instead. If so, how do I do?
Meanwhile, I think it may help if I post the code here:
===========================================
create or replace package PHAStatusRpt is
type pha_type is record(
name varchar2(50),
pha_start varchar2(12),
current_step varchar2(50),
dates varchar2(25),
last_status varchar2(20)
pha_rec pha_type;
procedure PHAStatusData(ret_parm OUT pha_type);
end PHAStatusRpt;
create or replace package body PHAStatusRpt is
procedure PHAStatusData(ret_parm OUT pha_type) is
BEGIN
SELECT name,
TO_CHAR(DECODE(NVL(current_pha_step_name,'~'),'~',last_pha_date,current_pha_start),'mm/dd/yyyy') pha_start,
DECODE(NVL(current_pha_step_name,'~'),'~','Complete',current_pha_step_name) current_step,
DECODE(NVL(current_pha_step_name,'~'),'~',TO_CHAR(last_pha_date,'mm/dd/yyyy'),pp_date) dates,
DECODE(NVL(current_pha_step_name,'~'),'~',null,last_pha_status) last_status
INTO pha_rec
FROM (SELECT pfeed_name||' ('||TO_CHAR(pfeed_dob,'mm/dd/yyyy')||')' ||'('||SUBSTR(pers_ssn,5,4)||')' name,
current_pha_start,
current_pha_step_name,
last_pha_date,
last_pha_status,
TO_CHAR(pp.start_date,'mm/dd/yyyy')||'-'||NVL(TO_CHAR(pp.end_date,'mm/dd/yyyy'),'n/a') pp_date
FROM v_pers_unit pu, personnel_readiness pr, person_processes pp
WHERE pu.pers_pers_id=pr.pers_id AND pr.current_pha_step_pp_id=pp.pp_id(+) AND cmdstr_cs_id=95990)
ORDER BY name;
end PHAStatusData;
end PHAStatusRpt;
SQL> exec phastatusrpt.phastatusdata
BEGIN phastatusrpt.phastatusdata; END;
ERROR at line 1:
