You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order ON customer.CustomerID=order.CustomerID LIMIT 0, 30' at line 2

What I have tried:

SELECT Customer.name, Customer.sex, Customer.address, order.orderDATE, Customer.nationality
FROM Customer INNER JOIN order ON customer.CustomerID=order.CustomerID

ORDER is a reserved word in MySQL. To use it as a table name, you need to quote the name everywhere you reference it.

SQL

SELECT Customer.name, Customer.sex, Customer.address, `order`.orderDATE, Customer.nationality
FROM Customer INNER JOIN `order` ON customer.CustomerID = `order`.CustomerID

As Griff suggested, changing your table name to Orders would also resolve the problem.

Try:

SQL

SELECT c.name
     , c.sex
     , c.address
     , o.orderDATE
     , c.nationality
FROM Customer c
INNER JOIN Order o
        ON c.CustomerID = o.CustomerID;

But I'd change a few things.
1) Make your table name plural: Customers not Customer; Orders not Order: this reflects that the tables contain multiple items rather than a single Customer or a single Order.
2) Change CustomerID in your Customers table to just ID, and OrderID to just ID in your Orders table. You can't mix 'em up because you have to specify the table they come from Via FROM or JOIN, so why duplicate information via the column name?
Your JOIN then becomes:

SQL

ON c.ID = o.CustomerID;
