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

这是一个实用的解决方案，它不是那么优雅的。如果您想以这种方式看到它，但它可以工作，并且您可以使它成为一个函数和/或存储过程，只需要几个参数......

首先，我们需要一个包含一些记录的表，任何表。我们将使用此表，就像行号表一样。（你需要在你想要显示的相同数月内需要尽可能多的行，有一张大桌子更好）＆gt;＆gt;

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

这将告诉你，在你的实例上有大多数记录的前100个表，我在这个例子中使用了mysql.help表，默认情况下，它带有几千条记录，而且它有＆＃39; s总之那......

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);

说明：

1.设定日期变量 2.设置月份值，用于添加月份 3.为每一行选择一个日期（我们在同一行添加一个月并增加月份变量） 4.过滤范围之间的日期 5.输出格式化日期。

这是最终输出＆gt;＆gt;

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

以下 SQL 对我的 MYSQL 有所帮助。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))
