how to write a query in MySql

Answer 1

I don't know how your relation looks like but if I get it right you want to SUM one column over the past 2 or 3 days which will be something like:

SELECT FORMAT(SUM(yourColumnName)
FROM tableName
WHERE entry.date >= CURDATE() - INTERVAL 2 days

For 3 days you have to set INTERVAL 3 days
