使用几个月的Mysql Date字段搜索来查找即将到来的生日

Question

I am trying to fins 'upcoming birthdays' of the users present in the Database.

I can able to fine the users upcoming birthday only till 12 month (Dec).

What if I need to find the upcoming birthday of next year.

My Query:

SELECT c.F_CONTACT_ID,
       c.F_CONTACT_NAME,
       c.F_CONTACT_FNAME,
       DATE_FORMAT(c.F_DOB, '%d/%m') F_DOB
FROM t_contact c
WHERE DATE_FORMAT(F_DOB, '%m') >= '08'
GROUP BY c.F_CONTACT_ID
ORDER BY c.F_DOB ASC LIMIT 0 ,
                           10

How can I find the upcoming birthday of the users who born on 'January' because the

DATE_FORMAT(F_DOB, '%m') >= '08'

can able to check till 12th month.

Can some one help me?

I have no idea why you have a group by . I would do this with an order by and limit :

SELECT c.F_CONTACT_ID,
       c.F_CONTACT_NAME,
       c.F_CONTACT_FNAME,
       DATE_FORMAT(c.F_DOB, '%d/%m') F_DOB
FROM t_contact c
ORDER BY (case when month(c.F_DOB) >= '08' then month(c.F_DOB)
               else month(c.F_DOB) + 12
          end)
LIMIT 0, 10;

That is, add "12" to the month numbers for next year. Note: this doesn't take the day of the month into account because your original query does not.
