我的SQL请求返回的NULL

Question

I have 3 tables :

I would like to display city and postal code, but for the postal code, I obtain NULL.

This is my sql request :

SELECT pays_cp_ville.*, villes.libelle, codes_postaux.code_postal FROM pays_cp_ville
        LEFT JOIN codes_postaux
            ON pays_cp_ville.ville_id = codes_postaux.id
        LEFT JOIN villes
            ON pays_cp_ville.ville_id = villes.id
        WHERE pays_cp_ville.code_postal_id = 11 AND pays_cp_ville.ville_id = 43672

this is the result :

Answer 1

I did a mistake in my sql request :

Error : pays_cp_ville.ville_id = codes_postaux.id

Correction : pays_cp_ville.code_postal_id = codes_postaux.id
