mysql中获取两个日期之间的连续日期列表的sql

应用：做报表的时候，查询的日期数据缺少某些日期的，补全日期信息的时候可用，用左外或右外连接补全
- 1.创建一个中间日期表

 CREATE TABLE num (i int);
 INSERT INTO num (i) VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9);

2.查询sql

select adddate('2012-09-01', numlist.id) as 'date' from 
 (SELECT n1.i + n10.i*10 + n100.i*100 AS id FROM num n1 cross join
     num as n10 cross join num as n100) as numlist 
       where adddate('2012-09-01', numlist.id) <= '2012-09-10';
