PostgreSQL inkrementella datum?

Du kan gå med med en generate_series utdata:

select
    '2013-05-01'::date + g.o AS "date with offset"
from
    generate_series(0, 30) AS g(o)

Utdata:

"2013-05-01"
"2013-05-02"
"2013-05-03"
...
"2013-05-29"
"2013-05-30"
"2013-05-31"

Eller... en enklare metod efter att ha definierat en ny lagrad procedur :)

CREATE OR REPLACE FUNCTION generate_series(date, date) RETURNS
SETOF date AS $$
SELECT $1 + g.s
FROM generate_series(0, ($2 - $1)) AS g(s);
$$ LANGUAGE SQL IMMUTABLE;

Kalla det bara så här:

SELECT * FROM generate_series(start_date, end_date);
