How to get first day of every corresponding month in mysql?

Question

I want to get first day of every corresponding month of current year. For example, if user selects \'2010-06-15\', query demands to run from \'2010-06-01\' instead of \'2010

Answer 1

You can use DATE_FORMAT() function in order to get the first day of any date field.

SELECT DATE_FORMAT(CURDATE(),'%Y-%m-01') as FIRST_DAY_CURRENT_MONTH 
FROM dual;

Change Curdate() with any other Date field like:

SELECT DATE_FORMAT(purchase_date,'%Y-%m-01') AS FIRST_DAY_SALES_MONTH 
FROM Company.Sales;

Then, using your own question:

SELECT *
FROM
  hrm_attendanceregister
WHERE
hrm_attendanceregister.Date) >=
 DATE_FORMAT(CURDATE(),'%Y-%m-01')

You can change CURDATE() with any other given date.
