title: In MySQL, can you check if a field is NULL or empty using only one comparison?
body: <p>If I want to check to see if a field is NULL or empty using a MySQL query, I know I can do something like this:</p>
  
  <pre><code>column = '' OR column IS NULL
  </code></pre>
  
  <p>However, is there any way to check this without doing two separate comparisons?</p>
