Question

I’ve a ‘items’ table with the following structure:

id, person_id, active

and ‘people’ table with id and name columns.

I want to order by most active items and join the people.name column to sql.

I tried to do something like that, but it’s not working:

SELECT people.id, COUNT(*) as items_count
FROM items, people
WHERE items.active = true AND people.id = items.person_id
GROUP BY items.person_id
ORDER BY items_count DESC

Answer 1

Use Joins this will match the condition. Order by items_count will give you most active user

Select people.id, COUNT(items.active) as items_count
FROM items
LEFT JOIN people on  people.id = items.person_id
WHERE items.active = true
GROUP BY people.id
ORDER BY items_count DESC
