Mysql: Find max and minimum date in a month

Recently I was looking for a quick way to find the first and last day of a  month, given any date from that month.
Michael Williamson seem to have a quick and fugly solution, which works quiet well.

Thanks Miachael.


Michael’s Blog » Blog Archive » MySQL number of days in a month

select date_add(concat(year(curdate()),'-',month(curdate()),'-','1'), interval 0 day) as mo_start,
date_sub(date_add(concat(year(curdate()),'-',month(curdate()),'-','1'), interval 1 month), interval 1 day) as mo_end;

Update: The same thing can be achieved by replacing curdate() with "now()". Here is the modified query.

select date_add(concat(year(now()),'-',month(now()),'-','1'), interval 0 day) as mo_start,
date_sub(date_add(concat(year(now()),'-',month(now()),'-','1'), interval 1 month), interval 1 day) as mo_end;
