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

I would use something similar to this:

DECLARE @DATEFROM AS DATETIME
DECLARE @DATETO AS DATETIME
DECLARE @HOLDER TABLE(DATE DATETIME)

SET @DATEFROM = '2010-08-10'
SET @DATETO = '2010-09-11'

INSERT INTO
    @HOLDER
        (DATE)
VALUES
    (@DATEFROM)

WHILE @DATEFROM < @DATETO
BEGIN

    SELECT @DATEFROM = DATEADD(D, 1, @DATEFROM)
    INSERT 
    INTO
        @HOLDER
            (DATE)
    VALUES
        (@DATEFROM)
END

SELECT 
    DATE
FROM
    @HOLDER

Then the @HOLDER Variable table holds all the dates incremented by day between those two dates, ready to join at your hearts content.
