title: Select from a table where fields don't match conditions
body: <p>I'm just wondering what kind of SQL command I could execute that would select all items from a certain table where column A is not equal to <code>x</code> and column B is not equal to <code>x</code></p>
  <p>Something like:</p>
  <pre><code>select something from table
  where columna does not equal x and columnb does not equal x
  </code></pre>
  <p>Any ideas?</p>
