Question

I want to create a graph of items on a certain day using data from a MySQL database. I have the query

SELECT * FROM activities 
WHERE timestamp BETWEEN UNIX_TIMESTAMP() - 24 * 3600 * 7 
    AND UNIX_TIMESTAMP() - 24 * 3600 * 6

to select items from x days ago (where the 7 and 6 can vary in order to select the day), but it’s returning an empty set in my database for some reason.

Answer 1

Try below:

 SELECT * FROM activities
 WHERE  date(timestamp) between start_date
 and DATE_SUB(start_date,interval x day))

Replace start_date with your startdate and x with interval
