Answer 1

该查询选择2011年的所有星期日。将其展开为您需要的年份，并将此选择插入到您选择的表中。

select a.Date 
from (
    select DATE('2011-12-31') - INTERVAL (a.a + (10 * b.a) + (100 * c.a)) DAY as Date
    from (select 0 as a 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) as a
    cross join (select 0 as a 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) as b
    cross join (select 0 as a 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) as c
) a
where DAYOFWEEK(a.Date)=1 and a.Date between '2011-01-01' and '2011-12-31'
