title: MySQL - How do I enter NULL?
body: <p>In SQL, I know I can do:</p>
  <pre><code>UPDATE TableA SET MyColumn=NULL
  </code></pre>
  <p>But, how do I enter <code>NULL</code> into a cell graphically? I tried entering 'null' and 'NULL' and '' (nothing/empty string) into the MySQL Query Browser with no success.</p>
