In TABLE Orders, which field (i.e. column heading) is identical to the field in TABLE Employees? and TABLE Customers? and TABLE Shippers? Please list all you can find in the format like Orders.field1 = Employees.field2, etc.
* Clarification: consider the identity in terms of contents but not the field names and allow combinations of fields in the same table; e.g., Orders.fieldnameX = Employees.fieldnameY + Employee.fieldnameZ
