Here is a SQLFiddle demo

select DATE_ADD('2012-12-01', INTERVAL ROW DAY) as Date,
row+1  as DayOfMonth from

(
SELECT @row := @row + 1 as row FROM 
(select 0 union all select 1 union all select 3 
        union all select 4 union all select 5 union all select 6) t1,
(select 0 union all select 1 union all select 3 
        union all select 4 union all select 5 union all select 6) t2, 
(SELECT @row:=-1) t3 limit 31
) b
where 
DATE_ADD('2012-12-01', INTERVAL ROW DAY)
between '2012-12-01' and '2012-12-31'
and
DAYOFWEEK(DATE_ADD('2012-12-01', INTERVAL ROW DAY))=1
