'How to attribute value to row based on nearest date
I'm attempting to attribute a value for "revenue" to a row based on the closest run_date, looking forwards in time. I'm using a date range as a join condition to only join rows within a 10 day "lookahead" period with the below....
SELECT
*
FROM t1
INNER JOIN t2 ON t1.id = t2.id
AND t2.date BETWEEN t1.run_date AND DATE_ADD(t1.run_date, INTERVAL 10 DAY)
The far right table is what I'm trying to achieve:
Does anybody have any advice as to how to get my intended result? (Far right table of the image)
I have a SQL fiddle here if anyone is interested in helping out.
