如何获取两个日期之间的所有日期？

Question

请看看我的books表：

books

+-----+----------+------------+------------+ 
| id | venue_id | from_date | to_date | 
+-----+----------+------------+------------+ 
| 1 | 8  | 2015-07-21 | 2015-07-28 | 
| 2 | 5  | 2015-08-03 | 2015-08-25 | 
+-----+----------+------------+------------+ 

我要查看from_date和to_date之间的所有日期安排venue_id = 8

我的输出应该是：

Array 
(
    [0] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-21 
     ) 
    [1] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-22 
     ) 
    [2] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-23 
     ) 
    [3] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-24 
     ) 
    [4] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-25 
     ) 
    [5] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-26 
     ) 
    [6] => Array 
     (
      [id] => 1 
      [venue_id] => 8 
      [today] => 2015-07-27 
     ) 
) 

today计算从from_date日期到to_date日期。但是我的想法对于那个查询是空白的。如何编写一个MySQL查询来获得像上面显示的输出结果？

Answer 1

以下查询应该用来获得所需的结果。 select * from books where venue_id = 8 and from_date> ='2015-07-21'and to_date < ='2015-07-27'

Answer 2

我想下面的查询应该可以获取结果。虽然我还没有测试过这个查询。

select b.id,b.venue_id,d.date from books b 
join 
(select a.Date, "8" as venue_id2 
from (
select curdate() - INTERVAL (a.a + (10 * b.a) + (1000 * 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 a.Date between '2010-01-20' and '2010-01-24') d on d.venue_id2 = b.venue_id and b.venue_id = 8
