title: Equivalent to minus in netezza
body: <p>I want to compare data between two different db tables in netezza. In oracle we can do that by minus operator. How can the same operation be done in netezza.</p>
  
  <pre><code>SELECT CUSTOMER_SRC_ID,CUSTOMER_SRC_DESC FROM  CIDB_SIT..CUSTOMER_SRC 
  MINUS 
  SELECT CUSTOMER_SRC_ID,CUSTOMER_SRC_DESC FROM EDW_SIT..CUSTOMER_SRC
  </code></pre>
  
  <p>Seems like it doesn't work in netezza. Can any one help me find the equivalent query in netezza?</p>
