SQL select and join 4 tables
-1
I'm new to SQL, trying to join 4 tables pictured below:
Here's what I have, but I don't currently have access to the SQL server (its down, and I don't own it so I just have to wait).
SELECT customerName, address, address2, postalCode, phone, country, city
FROM [CUSTOMER] C JOIN ADDRESS A ON C.addressId = A.addressId
JOIN CITY I ON A.cityId = I.cityId
JOIN COUNTRY P ON P.countryId = I.countryId");
Is this the proper way to join my tables?

Yes. Why? Btw. please edit your question and provide table structures in text form. There is absolutelly no good reason to use pictures just to post text, only downsides - ie content of pictures can't be indexed by search engines.

Looks fine. CUSTOMER doesn't need [ or ], that's a Microsoft SQL server syntax.

Probably best not to use the SO people to validate SQL, its a bit lazy. Install a MySQL locally or use db-fiddle.com / sqlfiddle.com / dbfiddle.uk to experiment with.
