Extract difference-Oracle Minus operation.

[#1]

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.

m3:

LOAD sqlyearlist as resultyearlist

Resident m1 where not exists(qvdyearlist, sqlyearlist);

edit: changed exists arguments
