Question
I have build a view
with following query.
SELECT TRUNC(sysdate - (365), 'YYYY') + (level-1) AS the_day
FROM dual
CONNECT BY level <= to_number(TO_CHAR(last_day(add_months(TRUNC(sysdate, 'YYYY'),11)), 'DDD'))
above query return output like below.

FROM dual
CONNECT BY level <=
to_number(TO_CHAR(last_day(add_months(TRUNC(sysdate, 'YYYY'), 11)),
'DDD'))
