SELECT 
    SUM(dischargecount) AS dis, MONTHNAME(dischargedate) AS n
FROM
    user
WHERE
    DATE(dischargedate) BETWEEN '$from' AND '$to'
GROUP BY MONTH(dischargedate)


SELECT 
    COUNT(DISTINCT response_user) AS val1,
    MONTHNAME(response_on) AS m
FROM
    response
WHERE
    response_on BETWEEN '$from' AND '$to'
GROUP BY MONTH(response_on)

I want to execute the two queries as one.
