Question

I have the table products and the table product_comments (relationship with the table products: product_id). Now I would need to remove some products from table products and if this product has some records in the table product_comments, remove also those ones.

Is possible something like that do in PhpMyAdmin?

Answer 1

Try

delete p, c 
from products p
left outer join product_comments c on c.product_id = p.product_id
where p.product_id = 1
