Question

I am have a column of dates that I need to add a variable amount of days to. So I don’t think I can use the normal date_add (date, interval x day).

date          numOfDays
2001-01-01        5
2001-05-22        3
2002-03-04        2
...               ...

I’m basically looking for something like:

select date, numOfDays, (date + numOfDays) as newDate
from t1;

Answer 1

SELECT `date`,
       `numOfDays`,
       (`date` + INTERVAL `numOfDays` DAY) AS `newDate`
  FROM `t1`;
