I’m building a chart and I want to receive data for each month. Here’s my first request which is working: SELECT s.GSP_nom AS nom, timestamp, AVG( v.vote + v.prix ) /2 AS avg FROM votes_serve

You need DATE_ADD/DATE_SUB : AND v.date > (DATE_SUB(CURDATE(), INTERVAL 2 MONTH))
AND v.date < (DATE_SUB(CURDATE(), INTERVAL 1 MONTH))
should work.Beste Antwort · 64As suggested by A Star, I always use something along the lines of: DATE(NOW()) – INTERVAL 1 MONTH
Similarly you can do: NOW() + INTERVAL 5 MINUTE23I usually use DATE_ADD(CURDATE(), INTERVAL – 1 MONTH)
Which is almost same as Pekka's but this way you can control your INTERVAL to be negative or16
