Salesforce Service Cloud - Table Account NULL values - sql-server

Question

I'm trying to obtain data from Service Cloud Salesforce but when I select the table in SSMS, the data is all NULL, so probably I'm not specifying the right columns or table.
Salesforce Report Builder
Salesforce Source Editor (Visual Studio)
When I run the report in Salesforce I can see that the country and postal code data are filled in, but when I read the documentation, I don't find the main column "Country" neither "Mailing Zip/Postal Code".
For the Zip Code, in this example, since it's also filled in the data about Billing Postal Code, this one I could obtain in the extraction, but for the country I can't find a column named "country", only "BillingCountry" and "ShippingCountry", but these columns do not contain any information.
Documentation:
https://developer.salesforce.com/docs/atlas.en-us.234.0.object_reference.meta/object_reference/sforce_api_objects_account.htm
Can anyone help here? I need to add on the select in salesforce source editor (visual studio) the right column names to obtain the country and the zip code.
Thank you,

Your report mixes fields from Account and Contact joined together by Contact.AccountId = Account.Id. You could edit it and expand the left sidebar to see which field comes from which object.
Account has Billing and Shipping address (2 sets of fields with actual names becoming BillingCity, BillingStreet... And Contact has Mailing address and Other Address.
So that's 4 * 6 fields across 2 tables out of the box. Can be muddied up further if you have "Person Accounts" enabled (some contacts get paired up as 1:1 relation to account instead of 1:n, in something that behaves a bit like materialised view for MS SQL people?). Also admin could rename one of the fields (API Names of columns stay the same but you'd see different labels in report and UI), add custom address fields...
See how these queries work for you. Try them out in Salesforce Developer Console (in web UI), or VSCode first, not in that tool you have.
Pure contacts
SELECT Id, FirstName, LastName, MailingStreet, MailingCity, MailingPostalCode
FROM Contact
WHERE MailingPostalCode = '4465-613'
LIMIT 10
Pure accounts
SELECT Id, Name, BillingStreet, BillingCity, BillingPostalCode
FROM Contact
WHERE BillingPostalCode = '4465-613'
LIMIT 10
Now JOIN (for normal Salesforce, B2B, where Account is more like a company and Contact is more like employee)
SELECT Id, FirstName, LastName, MailingStreet, MailingCity, MailingPostalCode, Account.Name, Account.City
FROM Contact
WHERE MailingPostalCode = '4465-613' AND Account.BillingPostalCode = '4465-613'
LIMIT 10
And since your second screenshot looks like you do have person accounts (more like B2C model, with standalone "1 man companies" like freelancers, doctors working in multiple hospitals, students in education...) try this one too
SELECT Id, Name, BillingCity, BillingPostalCode, ShippingCity, ShippingPostalCode, PersonMailingCity, PersonMailingPostalCode, PersonOtherCity, PersonOtherPostalCode
FROM Account
WHERE IsPersonAccount = true
LIMIT 10
