2021-12-01 07:12:30     December    8521

the query im using is below

SELECT
  created_on as 'time',
  MONTHNAME(created_on) AS 'month_name',
  count(distinct id_number) AS "inc_number"
FROM test_reports
WHERE
   MONTH(created_on)
GROUP BY MONTH(created_on)
ORDER BY MONTH(created_on)

Please suggest the way to get all time should be first date of each month.

    working, thanks @verhie

    SELECT
  created_on as 'time',
  MONTHNAME(created_on) AS 'month_name',
  count(distinct id_number) AS "inc_number"
FROM test_reports
WHERE
   MONTH(created_on)
GROUP BY DATE_FORMAT(created_on, '%Y-%m-01')
ORDER BY MONTH(created_on)

    If you use GROUP BY and do not specify a column, MySQL will just use one of the created_on values from the ‘array’.
    Instead you should define the expected output of created_on and add it to your GROUP BY
    You could use something like DATE_FORMAT(created_on, '%Y-%m-01') to always display the first day of that month
