How can I show data which is greater than or equal to mysql table column month?

Question

I have 2 columns (there are more) in clients table.

conn_date     bill_date
=======================
2016-08-25    2016-09-04
2016-08-01    2016-09-03
2016-08-08    2016-09-01
2016-08-09    2016-09-01

Now I want to show all data if selected month is = (equal) or > greater then conn_date . I can get selected month from html select tag eg : 1, 2, 9.

For that purpose, I am using following query but it's showing data less than conn_date

"SELECT cbp.advance_amount, cbp.bill_month, cbp.due_amount, cbp.pay_amount, c.is_active, c.client_id, c.user_id, c.address, c.contact_no, zone.zone_name, package.package_name, c.monthly_bill, c.bill_date FROM clients 
AS c LEFT JOIN zone ON zone.zone_id = c.zone_id 
LEFT JOIN package ON package.package_id = c.package_id 
LEFT JOIN clients_pay_bill AS cbp ON cbp.client_id = c.client_id 
WHERE c.uid = '$uid' AND c.is_active = 1 
AND MONTH(c.conn_date) > $selected_month 

Using print_r

SELECT cbp.advance_amount, cbp.bill_month, cbp.due_amount, cbp.pay_amount,
c.is_active, c.client_id, c.user_id, c.address, c.contact_no, zone.zone_name, package.package_name, c.monthly_bill, c.bill_date 
FROM clients AS c 
LEFT JOIN zone ON zone.zone_id = c.zone_id 
LEFT JOIN package ON package.package_id = c.package_id 
LEFT JOIN clients_pay_bill AS cbp ON cbp.client_id = c.client_id 
WHERE c.uid = '6' AND c.is_active = 1 
AND MONTH(c.conn_date) > 4 AND c.zone_id != '' 
ORDER BY c.client_id DESC

Answer 1

Basically, I want to show data which is not less than conn_date of selected month

The mysql query for that is

SELECT * FROM clients WHERE MONTH(conn_date)<='".$selected_month."'

From the description of your problem, it sounds like you want:

select c.*
from clients c
where conn_date >= str_to_date(concat(date_format(now(), '%Y-%m'), '-01'))

This returns dates greater than the current time. If you want a particular month of a particular year:

select c.*
from clients c
where conn_date >= str_to_date(concat_ws('-', $year, $month, '01'))

I am not sure what your query does, because it uses several tables not mentioned in the question.
