Question

I need to modify my query to select information that is 1 day, 1 week old.
I have 2 tables one for votes and other for articles, and It should look at st_date from articles table.

Query

SELECT stories.*, SUM(votes.vote_value) as 'total_votes' 
FROM stories 
    JOIN votes ON stories.id = votes.item_name 
GROUP BY stories.id 
ORDER BY total_votes DESC LIMIT 10

Database Structure:

Stories table

Votes Table

Answer 1

A week is always 7 days, so you actually need data from 8 days old.

WHERE st_date >= DATE_SUB(NOW(), INTERVAL 8 DAY)

Your full query would be:

SELECT stories.*, SUM(votes.vote_value) as 'total_votes' 
FROM stories 
    JOIN votes ON stories.id = votes.item_name 
WHERE stories.st_date >= DATE_SUB(NOW(), INTERVAL 8 DAY)
GROUP BY stories.id 
ORDER BY total_votes DESC LIMIT 10
