Answer 1

SQLFiddle演示

select 
DATE_FORMAT(m1, '%b %Y')

from
(
select 
('2013-01-23' - INTERVAL DAYOFMONTH('2013-01-23')-1 DAY) 
+INTERVAL m MONTH as m1
from
(
select @rownum:=@rownum+1 as m from
(select 1 union select 2 union select 3 union select 4) t1,
(select 1 union select 2 union select 3 union select 4) t2,
(select 1 union select 2 union select 3 union select 4) t3,
(select 1 union select 2 union select 3 union select 4) t4,
(select @rownum:=-1) t0
) d1
) d2 
where m1<='2014-04-01'
order by m1

Answer 2

这是一个实际的解决方案，如果您想那样看，它并不是那么“优雅”，但是它可以工作，并且只需几个参数就可以使其成为函数和/或存储过程...

首先，我们需要一个包含一些记录的表，任何表。我们将使用该表作为行号表。（在您要显示的相同月份中，您将需要尽可能多的行，拥有较大的表会更好）>>

SELECT CONCAT(table_schema, '.', table_name) as schema_table, table_rows
FROM   information_schema.TABLES
order by 2 desc limit 0,100

这将告诉您实例上具有最多记录的前100个表，在此示例中，我使用的是mysql.help表，默认情况下，它带有几千条记录，并且始终存在...

set @start_date = '2013-01-23';
set @end_date = '2014-04-01';
set @months = -1;

select DATE_FORMAT(date_range,'%M, %Y') AS result_date from (
    select (date_add(@start_date, INTERVAL (@months := @months +1 ) month)) as date_range
    from mysql.help_topic a limit 0,1000) a
where a.date_range between @start_date and last_day(@end_date);

解释：

1.设置日期变量2.设置月份值（用于添加月份）3.为每行选择一个日期（我们在同一行中添加月份并增加月份变量）4.过滤范围之间的日期5.输出格式日期。

这是最终的输出>>
