Question

I have a table with

id int pk auto_inc | created int(11) | amount int | user_id int

I want to create a list of rows grouped by day totalling the amount field.

I have tried this:

SELECT created, sum(amount) as amount, id FROM total_log WHERE user_id = $this->user_id GROUP BY DAY(created)

This doesn’t give the right results. They are getting grouped into one row.

The date is saved from dd/mm/yyyy format to unix time stamp like 1349046000

Answer 1

SELECT 
    DATE(FROM_UNIXTIME(created)) as d, 
    sum(amount) as amount
FROM total_log 
WHERE user_id = $this->user_id 
GROUP BY d
