Extract difference-Oracle Minus operation.

Hi guys,

here i have a task- i want to get a difference between two tables in the third table. For example, if the table m1 contains rows: 2005,2006,2007,2008 and the table m2 contains: 2005, then the table m3 must contain:2006,2007,2008.

I've got the script which loads the first and the second tables:

m1:

Load *;

sql

select distinct year(orderdate) as sqlyearlist

from AdventureWorks2012.Sales."vSalesOrderHeader-July"

order by 1 asc;

m2:

LOAD Distinct year(OrderDate) as qvdyearlist

FROM Orders_*.QVD (qvd);

Appreciate any advises and solutions.
