How to get a list of months between two dates in mysql
SQLFiddle demo
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
this is a practical solution, it's not so 'elegant' if you wanna see it that way, but it works, and you can make it a function and/or a stored procedure, just with a couple of parameters...
first, we need a table with some records, any table. we're gonna use this table, just as a row number table. (you'll need as many rows for the same amount of months you wanna display, having a large table is better) >>
SELECT CONCAT(table_schema, '.', table_name) as schema_table, table_rows
FROM information_schema.TABLES
order by 2 desc limit 0,100
this will tell you, the top 100 tables with most records on your instance, i'm using the mysql.help table for this example, by default, this comes with some thousand records, and it's allways there...
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);
explained:
1. set date variales 2. set month value, for adding months 3. select for each row, a date (we add a month and increment the month variable on the same row) 4. filter dates that are between range 5. output formated dates.
this is the final output>>

Try this one:
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
