Thanks to IvanD. I've got a better solution which allowes you to create a specified calendar table. For example, if I'm trying to create a table of 2014-04, it looks like this:

SELECT (CURDATE() - INTERVAL c.number DAY) AS DATE
FROM 
(
    SELECT singles + tens + hundreds number FROM 
    ( 
        SELECT 0 singles
        UNION ALL SELECT   1 UNION ALL SELECT   2 UNION ALL SELECT   3
        UNION ALL SELECT   4 UNION ALL SELECT   5 UNION ALL SELECT   6
        UNION ALL SELECT   7 UNION ALL SELECT   8 UNION ALL SELECT   9
    ) singles JOIN 
    (
        SELECT 0 tens
        UNION ALL SELECT  10 UNION ALL SELECT  20 UNION ALL SELECT  30
        UNION ALL SELECT  40 UNION ALL SELECT  50 UNION ALL SELECT  60
        UNION ALL SELECT  70 UNION ALL SELECT  80 UNION ALL SELECT  90
    ) tens  JOIN 
    (
        SELECT 0 hundreds
        UNION ALL SELECT  100 UNION ALL SELECT  200 UNION ALL SELECT  300
        UNION ALL SELECT  400 UNION ALL SELECT  500 UNION ALL SELECT  600
        UNION ALL SELECT  700 UNION ALL SELECT  800 UNION ALL SELECT  900
    ) hundreds
    ORDER BY number DESC
) c  
WHERE c.number BETWEEN 
DAYOFYEAR(NOW()) - DAYOFYEAR('2014-04-01')-  DAY(LAST_DAY('2014-04-01')) +1
AND 
DAYOFYEAR(NOW()) - DAYOFYEAR('2014-04-01')
