php - 如何显示大于或等于mysql表列月份的数据？

Question

我在 clients 表中有 2 列(还有更多列)。

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

现在，如果所选月份 =(等于)或 > 大于 conn_date，我想显示所有数据。我可以从 html select 标签 e 中获取选定的月份。 G。 :1、2、9。

为此，我使用以下查询，但它显示的数据小于 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 

使用 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 

选定月份图像

Answer 1

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

mysql 查询是

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