Need Day wise leave statistic report.

Hi All,
I am trying to develop new day wise leave statistic report, as attachment , please check below code and suggest.
CREATE TABLE GET_DATES (DATE_START DATE,DATE_END DATE,PERSON_ID NUMBER);
INSERT INTO GET_DATES
VALUES (TO_DATE('11-MAY-2014'), TO_DATE('04-JUN-2014'),26876);
INSERT INTO GET_DATES
VALUES (TO_DATE('22-JAN-2017'), TO_DATE('22-MAR-2017'),26876);
COMMIT;
1. select date_start, date_end, date_end - date_start +1 days FROM GET_DATES;
the below query is working fine for one row, if more than 1 row its records are more than million.
but the desired output is to get correct days as attached file.
2. Select level - 1 lvl , date_start, date_end
FROM
(select date_start, date_end FROM GET_DATES
WHERE ROWNUM = 1)
connect by level <= (date_end - date_start)+ 1
3. Final query
select * from(
select date_start + lvl date_,
Trim(to_char(date_start + lvl, 'Day')) current_day_,
to_char(date_start + lvl, 'mm') month_,
to_char(date_start + lvl, 'YYYY') Year_
from (
Select level - 1 lvl , date_start, date_end
FROM
(select date_start, date_end FROM GET_DATES
WHERE ROWNUM = 1)
connect by
level <= (date_end - date_start)+ 1))
pivot (count(date_)date_ for current_day_ in
('Sunday' Sun,'Monday' Mon ,'Tuesday' Tue,'Wednesday' Wed,'Thursday' Thu,'Friday' Fri,'Saturday' Sat))
order by 2, 1;
“Thank you in advance”

Connect by with the condition on only level is applicable to a single-row source. Otherwise, the source rows are multiplied by each level.
Use join on correlated subquery with dual connect by (cross apply).

A couple of hints:
1) This forum is for discussion of the use of the SQL Developer GUI tool. Your question is purely a SQL question. Better asked at https://community.oracle.com/tech/developers/categories/3063-general_questions1
2) When you post code, it is much (MUCH) preferred that you format it so that it is more easily read:
CREATE TABLE GET_DATES (DATE_START DATE,DATE_END DATE,PERSON_ID NUMBER); INSERT INTO GET_DATES VALUES (TO_DATE('11-MAY-2014'), TO_DATE('04-JUN-2014'),26876); INSERT INTO GET_DATES VALUES (TO_DATE('22-JAN-2017'), TO_DATE('22-MAR-2017'),26876); COMMIT; select date_start, date_end, date_end - date_start +1 days FROM GET_DATES;
Notice also that your TO_DATE is lacking a format mask. That is just asking for trouble.
