title: How to multiply two columns and have product as another column and PERSIST it?
body: <p>How would I go about when creating a new table and the columns, to have one column be the product of two other columns and persist it?</p>
  
  <p>For example:</p>
  
  <pre><code>CREATE TABLE Test(
  column1 int NOT NULL,
  column2 int NOT NULL,
  column3 AS (column1 * column2) PERSISTED NOT NULL
  )
  </code></pre>
  
  <p>Is this the correct way in doing it?</p>
  
  <p>Thanks</p>
