Writing a recursive query to find out all dates between two given date

--Declaring the required variables
DECLARE @fromdate DATETIME
DECLARE @todate DATETIME
SET @fromdate = '2010-01-01'
SET @todate = '2010-01-10'

--Query to fetch all the dates between two given date
;WITH tmpinfo(tmpdt) AS
(SELECT @fromdate
UNION ALL
SELECT tmpdt + 1
FROM tmpinfo
WHERE tmpdt < @todate)
SELECT * FROM tmpinfo OPTION (MAXRECURSION 0);

  3. MySQL reports about syntax error:
    [ERROR in query 1] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '--Declaring the required variables
    DECLARE @fromdate DATETIME
    DECLARE @todate ' at line 1
    [ERROR in query 2] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WITH tmpinfo(tmpdt) AS
    (SELECT @fromdate
    UNION ALL
    SELECT tmpdt + 1
    FROM tmp' at line 1
