Række for hver dato fra startdato til slutdato

Brug en rekursiv subquery-factoring-sætning:

WITH ranges ( start_dt, end_dt, id ) AS (
  SELECT start_dt, end_dt, id
  FROM   table_name
UNION ALL
  SELECT start_dt + INTERVAL '1' DAY, end_dt, id
  FROM   ranges
  WHERE  start_dt + INTERVAL '1' DAY <= end_dt
)
SELECT start_dt,
       id
FROM   ranges;

Hvilket for dine eksempeldata:

CREATE TABLE table_name ( start_dt, end_dt, id ) AS
SELECT DATE '2013-04-05', DATE '2013-04-09', 1 FROM DUAL
