title: XOR in SQL Server
body: <p>I have to display the countries that are big by area or big by population but not both and Show name, population and area. Basically it's a XOR operation if i am not wrong.</p>
  <p>A country is big if it has an area of more than 3 million sq km or it has a population of more than 250 million.</p>
  <p>I have tried this</p>
  <pre><code>SELECT name, population, area
  FROM world
  WHERE (area &gt; 30000000 | population &gt; 25000000) &amp;
        (area &lt; 30000000 &amp; population &lt; 25000000)
  </code></pre>
