MySQL:如果小于now()加1个月,选择日期加6个月

I have a given date:

2013-12-20

This is an issue date of a product where the product expiries in 6 months from the date of issue. The expiration date it is not stored so I want to check from the given issue date if it is expiring in the next month of now().

So my guess would be to add 6 months to the issue date and check now + interval of 1 month if it is expiring?

Here is what I tried:

SELECT * FROM `products` WHERE DATE_ADD(`issue_date`,INTERVAL 6 MONTH) 
< DATE(NOW() + INTERVAL 1 MONTH) ORDER BY `issue_date` ASC

What I'm I doing wrong?

    here's a suggestions which might help
    $date = date("y-m-d", strtotime(" +6 months"));
    this will result in date 6 months later from current date:
    similarly,
    for one month from current date
    $date = date("y-m-d", strtotime(" +1 months"));
