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

这是一个实用的解决方案，如果您想以这种方式看待它，它并不是那么“优雅”，但它可以工作，您可以将其设为函数和/或存储过程，只需几个参数......

首先，我们需要一个包含一些记录的表，任何表。我们将使用这个表，就像一个行号表。（在要显示的相同月份内，您需要尽可能多的行，最好有一个大表）>>

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

这会告诉你，你的实例上记录最多的前 100 个表，我在这个例子中使用 mysql.help 表，默认情况下，它有几千条记录，而且它总是在那里......

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. 为每一行选择一个日期（我们添加一个月份并在同一行上增加月份变量） 4. 过滤范围之间的日期 5. 输出格式化日期。

这是最终输出>>

January, 2013
February, 2013
March, 2013
April, 2013
May, 2013
June, 2013
July, 2013

September, 2013
October, 2013
November, 2013
December, 2013
January, 2014
February, 2014
March, 2014
April, 2014

Answer 3

试试这个：

select aDate from (
  select @maxDate - interval (a.a+(10*b.a)+(100*c.a)+(1000*d.a)) day aDate 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) a, /*10 day range*/
  (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) b, /*100 day range*/
  (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) c, /*1000 day range*/
  (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) d, /*10000 day range*/
  (select @minDate := '2001-01-01', @maxDate := '2002-02-02') e
) f
where aDate between @minDate and @maxDate

下面的这个 SQL 对我的 MYSQL 有帮助。您可以根据需要更新 curdate() 值以获取任何月份的日期列表。链接：（https://www.programmersought.com/article/26156494713/）

SELECT DATE_FORMAT(DATE_SUB(last_day(curdate()), INTERVAL xc-1 day), '%Y-%m-%d') as date
FROM ( 
            SELECT @xi:=@xi+1 as xc from 
            (SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6) xc1, 
            (SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6) xc2,  
            (SELECT @xi:=0) xc0 
) xcxc) x0 where x0.date >= (select date_add(curdate(),interval-day(curdate())+1 day))
