title: Mysql - Get records where column value is everything but a specific value
body: <p>I have two tables:</p>
  
  <p>Car</p>
  
  <p>Columns:</p>
  
  <pre><code>id
  </code></pre>
  
  <p>Wheel</p>
  
  <p>Columns:</p>
  
  <pre><code>id | car_id | tire_pressure
  </code></pre>
  
  <p>A car has many wheels.</p>
  
  <p>I want to select all <code>Car</code>s that does not have a <code>Wheel</code> with the <code>tire_pressure</code> of 'low' so it can have many other wheels, but if it does not have a wheel with the <code>tire_pressure</code> of 'low' then I would want it to be returned in the query result.</p>
  
  <p>Can this be done in mysql?</p>
