plsql Trying to use number variable (year) to find fiscal year - sql

Question

Thanks for any help,
I am trying to build a stored procedure, in pl/sql, where i can load data from the fiscal year specified.
For example, fyloader(2013) would load pe.contact_date between 10/01/2012 to 09/30/2013. How can I do that?
Thank you again,
Will
create or replace procedure fyloader (
p_fiscal_year number
) as
begin
insert into schemax.tablex
(select distinct pe.pat_id as PATID,
pat.pat_mrn_id as PATMRNID,
pe.pcp_prov_id as PCPPROVID,
pe.department_id as DEPARTMENTID,
pe.contact_date as CONTACTDATE,
trunc((TO_DATE ('30-09-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS') - pat.birth_date)/365.25) AS AGE,
'' as AGEGROUP,
ce.financial_class as FINCLASS
from pat_enc pe
inner join patient pat on pe.pat_id = pat.pat_id
inner join clarity_dep b on b.department_id = pe.department_id
left join clarity_ser cs on pe.visit_prov_id = cs.prov_id
left join zc_def_division zc on cs.def_division_c = zc.def_division_c
inner join hsp_account ha on pe.hsp_account_id = ha.hsp_account_id
inner join clarity_epm ce on ha.primary_payor_id = ce.payor_id
where
pe.enc_type_c = '101' --include office visits only (add 1001 if you require VirVis)
and (pe.appt_status_c = 2 OR pe.appt_status_c is null)
and (pat.pat_status_c =1 or nvl(pat.pat_status_c,99999) = 99999)
and pe.contact_date between TO_DATE('1-OCT-2012','DD-MON-YY') and TO_DATE('30-SEP-2013','DD-MON-YY')
and (zc.def_division_c in (26,91,266,329,330,331,332,333,389,402)
or pe.visit_prov_id = pe.pcp_prov_id)
and ce.financial_class in ('1','3')
and b.DEPARTMENT_ID in (200101,200102,200104,200201,200202,200204,
200220,200301,200302,200304,200319,200401,200402,200404,200501,200601,

You can use the 'to_date' and 'add_months' functions to get the result you need. Assuming your financial year is 01-Jul -> 30-Jun the below code will give you what you want.
declare
p_input_year number := 2014;
v_fy_start_date date;
v_fy_end_date date;
begin
v_fy_start_date := add_months(to_date('0101'||p_input_year,'DDMMYYYY'), -6);
v_fy_end_date := add_months(to_date('0101'||p_input_year,'DDMMYYYY'), 6) - 1;
dbms_output.put_line('FY Start: ' || v_fy_start_date);
dbms_output.put_line('FY End: ' || v_fy_end_date);
end;
The results of dbms_output being:
FY Start: 01-JUL-13
FY End: 30-JUN-14
If your financial year dates are different you will need to adjust the -6 / 6 passed to add_months.
