How to select last 6 months from news table using MySQL

Question

Use DATE_SUB

 .... where yourdate_column > DATE_SUB(now(), INTERVAL 6 MONTH)

Try this:

select *
  from table 
 where your_dt_field >= date_sub(now(), interval 6 month);

Query reads: give me all entries in table where the field corresponding to the entry date is newer than 6 months.

I tried @user319198 answer to display last 6 months (sum of) sales, it worked but I faced one issue in the oldest month, i do not get the sales amount of the whole month. The result starts from the equivalent current day of that month.

Just I want to share my solution if any one interested:-

yourdate_column > DATE_SUB(now(), INTERVAL 7 MONTH)
limit 6

Also it will be great if anyone has better solution for my case J.

You can also use TIMESTAMPDIFF

    TIMESTAMPDIFF(MONTH, your_date_column, now()) <= 6 )

To me, this looks like a solution as I'm using it with MariaDB, take a look at WHERE clause:

SELECT MONTH(yourTimestampOrDateColumn) AS MONTH, USER, ActionID, COUNT(*) AS TOTAL_ACTIONS, ROUND(SUM(totalpoints)) AS TOTAL_PTS
FROM MyTable
WHERE MONTH(yourTimestampOrDateColumn) BETWEEN MONTH(CURDATE() - INTERVAL 6 MONTH) AND MONTH(CURDATE())
GROUP BY MONTH;

On the image we see only months where user had actual data recorded in a DB (thus showing only 4 months instead of 6).

So this month is 10th (October), 6 months ago was 4th month (April), thus query will look for that interval (from 4 to 10).

You can get last six month's data by subtracting interval of 6 month from CURDATE() (CURDATE() is MySQL function which returns Today's date).

SELECT * FROM table 
         WHERE your_date_field >= CURDATE() - INTERVAL 6 MONTH;

Or you can use BETWEEN operator of MySQL as Below:

SELECT * FROM table 
         WHERE your_date_field BETWEEN CURDATE() - INTERVAL 6 MONTH AND CURDATE();
