Can someone to told me wich version of Northwind database is used for w3school SQL Tutorial, because every version of Northwind database that I find is not same as database in tutorial?
For example. Diference is in table Customers, where in Tutorial table have columns CustomerID, CustomerName, ContactName, Address, City, PostalCode and Country. And table Customer in almost all Northwind database wich I find have columns CustomerID, CompanyName, ContactName, ContactTitle, Address, City, Region, PostalCode, Country, Phone, Fax. Also, in tutorial table Customers CustomerID is number, and in my database, in table Customers CustomerID is string of five letters.
