How to get month name by month number inside the query using mysqli?

Question

I'm trying to get the count of added records by month. Following query is working fine

SELECT    COUNT(*) AS count_by_month, MONTH(date_added) AS in_month
FROM      `promotion` 
WHERE     YEAR(date_added) = '2016' 
GROUP BY  MONTH(date_added)

But above query is returning month number in the result, I wanted to get the month name like Jan , Feb instead of number. I tried following trick but it does not working.

    SELECT    COUNT(*) AS count_by_month, 
    MONTH(date_added) AS in_month, MONTHNAME(STR_TO_DATE(in_month, '%m'));
    FROM      `ws_promotion` 
    WHERE     YEAR(date_added) = '2016' 
    GROUP BY  MONTH(date_added)

Can anyone guide me how can fix the issue, i would like to appreciate if someone guide me regarding this. Thank You.

Try this:

SELECT    
    COUNT(*) AS count_by_month, 
    MONTH(date_added) AS in_month, 
    MONTHNAME(date_added)
FROM      `ws_promotion` 
WHERE     YEAR(date_added) = '2016' 
GROUP BY  MONTH(date_added)

Note: MONTHNAME(date) function expects date as argument.

Example:

mysql> SELECT MONTHNAME('2009-05-18');
+-------------------------+
| MONTHNAME('2009-05-18') |
+-------------------------+
| May                     | 
+-------------------------+
1 row in set (0.02 sec)

More: If you want to get month name from numbers then you can use STR_TO_DATE() to convert the number to a date, and then back with MONTHNAME()

SELECT MONTHNAME(STR_TO_DATE(7, '%m'));

+---------------------------------+
| MONTHNAME(STR_TO_DATE(7, '%m')) |
+---------------------------------+
| July                            |
+---------------------------------+
