How to decrease SQL Query from last 30 days until now?

Question

I am trying to get the amount of data for the last 30 days.

SELECT ( Now() - interval 1 month ), 
   Count(flightid) AS count 
FROM   flight 
WHERE  flightstatus = 0 
   AND flightvisibility = 1 
   AND flightvaliddate > Now() 
   AND flightvaliddate >= ( Now() - interval 1 month ) 

Right now this is working ok and it's giving me only 1 row that corresponds to the same day of last month.

What I would like is to get the remaining data from each day until now. How can I do this?

I am using MySQL.

Answer 1

The condition in the WHERE clause is wrong.

And since you want day wise data of last thirty days till now then you must have to use GROUP BY .

SELECT
    DATE(flightvalidate) AS flightValidateDate,
    Count(flightid) AS count
FROM
    flight
WHERE
    flightstatus = 0
    AND flightvisibility = 1
    AND DATE(flightvaliddate) >= CURDATE() - INTERVAL 1 MONTH 
GROUP BY flightValidateDate
ORDER BY flightvalidate
