no values if null in the referenced table sql access

问题

I have table that "reviewers" as a id and a name

ID |  Name
1  |  Coolboy

Now i have table "Orders" that has a foreign key to the "reviwers" table

Order No  | Date | ID  |

now some the fields in the "orders" table is null,

so in that case the sql is not working:

select o.[order no], o.[date], r.[name] orders o, reviewers r where o.ID = r.ID 

If there are null values in the "Orders" table then how to show the rows.

how to mix this query with a where clause:

SELECT O.[Order No], O.[Date], [R.Name], i.[inv_date] FROM Reviewers R, Invoices i
LEFT JOIN Orders O ON O.ID = R.ID where  o.[inv_no] =  i.[inv_numb]

I have come up with a new question:

replace multiple left joins in access sql

Thanks
