I think you are asking the total number of days to be returned for a month. If you are trying to find the total number of days for current month, here is the query:

select timestampdiff(day,
concat(year(now()),'-',month(now()),'-01'),
date_add( concat(year(now()),'-',month(now()),'-01'), interval 1 month)).

If you want to externalize this using any programming language, externalize year and month in the code and replace that with now()
