mysql next date by day of one field - mysql

Question

i have a mysql customers table:
customer_id | customer_name | creation_date
1 | john | 2013-09-12 18:34:00
2 | banjo | 2013-01-11 14:34:00
what i would to achieve is to know the closest DAY in the current ot next month that match the creation_date field.
I.E if the current date is 2014-01-20, i would like to have the following result
customer_id | customer_name | creation_date | next_date
1 | john | 2013-09-12 18:34:00 | 2014-02-12
2 | banjo | 2013-01-11 14:34:00 | 2014-02-11

Answer 1

The following seems to work but not tested for edge cases:
SELECT
CURRENT_DATE AS cutoff_date,
date_column AS creation_date,
CASE
WHEN STR_TO_DATE(CONCAT_WS('-', YEAR(CURRENT_DATE), MONTH(CURRENT_DATE), DAY(date_column)), '%Y-%c-%e') >= CURRENT_DATE
THEN STR_TO_DATE(CONCAT_WS('-', YEAR(CURRENT_DATE), MONTH(CURRENT_DATE), DAY(date_column)), '%Y-%c-%e')
ELSE STR_TO_DATE(CONCAT_WS('-', YEAR(CURRENT_DATE), MONTH(CURRENT_DATE), DAY(date_column)), '%Y-%c-%e') + INTERVAL 1 MONTH
END AS next_date
FROM dates2
Results:
cutoff_date creation_date next_date

Answer 2

First calculate the wanted date, than use min/max to get the closest one. Maybe something like that:
-- If your stored date is always in year 2013
select CASE WHEN DATE_ADD(DATE_ADD(creation_date, INTERVAL 1 YEAR), INTERVAL 1 MONTH) < SYSDATE
THEN DATE_ADD(creation_date, INTERVAL 1 YEAR)
ELSE DATE_ADD(DATE_ADD(creation_date, INTERVAL 1 YEAR), INTERVAL 1 MONTH)
END AS next_date
from customers;
This will make your creation_date 2013-09-12 to 2014-10-12. But if you just want the day maybe this is useful?:
-- If your stored date is always in year 2013
select str_to_date(concat(date_format(curdate(),'%Y-%m'), date_format(creation_date,'%d')),'%Y-%m-%d') as next_date
from customers;
This should use the current year and month, but change just the day. You can use a CASE to check if the difference between the current or the next month is closer.

You can try this, in mysql you can use interval for perticuler increament date like:
select customer_id,customer_name,creation_date,(creation_date+interval 1 year) as next_date from customer_info;
if you want,
next year then use- (creation_date + interval 1 year)
next month then use- (creation_date + interval 1 month)
for perticular day use- (creation_date + interval 5 day)
