How do I get a count of associated rows in a left join in MySQL?

Question

I have two tables, a vehicle table with columns:

• id
• stock
• year
• make

Answer 1

In the way the anser suggests, you get repeated values of "vehicle". A better way, is to group results. Try without the JOIN :

SELECT 
    `vehicle`.`id`, 
    `vehicle`.`stock`, 
    `vehicle`.`year`, 
    `vehicle`.`make`, 
    `vehicle`.`model`, 
    `images`.`name`,
    (
        SELECT COUNT(*) 
        FROM `images` 
        WHERE `vehicle_id` = `vehicle`.`id`
    ) AS `image_count`
FROM `vehicle`

WHERE `images`.`default`
