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

Let me make it clear for everyone!

Task: Print 3 columns table:

1. Vehicles (titles) from vehicles table.
2. Amount of comments for each vehicle from comments table.
3. Amount of images for each vehicle from images table.

Expected output (just an example):

+----------------------+----------------+--------------+
|        title         | comments_count | images_count |
+----------------------+----------------+--------------+
| BMW X6               |             35 |            9 |
| Audi A6              |              3 |            5 |
| Volkswagen Passat B6 |             78 |            6 |
| Volkswagen Passat B5 |            129 |            4 |
+----------------------+----------------+--------------+

Solution:

SELECT 
    vehicles.title,
    (SELECT COUNT(*) FROM comments WHERE vehicles.id = comments.vehicle_id) AS comments_count,
    (SELECT COUNT(*) FROM images WHERE vehicles.id = images.vehicle_id) AS images_count
FROM vehicles
