We can split a string into substrings using PL/SQL built in functions SUBSTR(), INSTR() and LENGTH() together.

Follwing code snippets helps you in splitting a string into substrings.

Snippet to split string into pieces:::

CREATE OR REPLACE FUNCTION func_str_split(str_to_split IN OUT VARCHAR2
,str_delimiter IN VARCHAR2) RETURN VARCHAR2
IS
t_pos NUMBER;
t_len NUMBER;
t_strlen NUMBER;
t_strresult VARCHAR2(2000);
BEGIN
t_strresult := NULL;
IF str_to_split IS NOT NULL THEN
t_len := LENGTH(str_delimiter);
t_strlen := LENGTH(str_to_split);
t_pos := INSTR(str_to_split,str_delimiter);
IF t_pos > 0 THEN
t_strresult := SUBSTR(str_to_split,1,t_pos-1);
str_to_split := SUBSTR(str_to_split,t_pos+t_len,t_strlen);
ELSE
t_strresult := str_to_split;
str_to_split := NULL;
END IF;
END IF;
RETURN t_strresult;
END func_str_split;

Use following procedure to call above function:::

CREATE OR REPLACE PROCEDURE proc_str_split(str_to_split IN OUT VARCHAR2
,str_delimiter IN VARCHAR2)
IS
declare

END proc_str_split;

select
fg.request_group_name,e.executable_name,responsibility_key,user_concurrent_program_name
from fnd_responsibility r,
fnd_concurrent_programs_tl p,
fnd_request_group_units u,
fnd_request_groups fg,
fnd_executables e,
fnd_concurrent_programs fcp
where r.request_group_id=u.request_group_id
and u.request_group_id = fg.request_group_id
and u.request_unit_id = p.concurrent_program_id
and fcp.executable_id = e.executable_id
and user_concurrent_program_name like ‘%Period close value summary%’
and fcp.concurrent_program_id = p.concurrent_program_id

To find out various concurrent programs associated with certain responsibility, following query will be useful.

select user_concurrent_program_name  from fnd_concurrent_programs_tl
where concurrent_program_id in (
select request_unit_id from fnd_request_group_units
where request_group_id in (
select request_group_id from fnd_request_groups where request_group_id in (
select request_group_id from fnd_responsibility where responsibility_key like ‘%ORACLE_INVENTORY%’)
));
