Get a list of dates between two dates

Question

Using standard mysql functions is there a way to write a query that will return a list of days between two dates.

eg given 2009-01-01 and 2009-01-13 it would return

Answer 1

Borrowing an idea from this answer, you can set up a table with 0 through 9 and use that to generate your list of dates.

CREATE TABLE num (i int);
INSERT INTO num (i) VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9);

select affffdate('2009-01-01', numlist.id) as `date` from
(SELECT n1.i + n10.i*10 + n100.i*100 AS id
   FROM num n1 cross join num as n10 cross join num as n100) as numlist
where affffdate('2009-01-01', numlist.id) <= '2009-01-13';

This will allow you to generate a list of up to 1000 dates. If you need to go larger, you can add another cross join to the inner query.
