title: Boolean value '>=2' is not recognized
body: <p>I have a table with column1 as varchar datatype.
  I am trying to update the table as :</p>
  <pre><code>UPDATE &quot;DB&quot;.&quot;SCHEMA&quot;.&quot;TABLE&quot; SET COLUMN1='&gt;=2' WHERE COLUMN2='XXX';
  </code></pre>
  <p>I am getting error message as:</p>
  <blockquote>
  <p>Boolean value '&gt;=2' is not recognized</p>
  </blockquote>
  <p>COLUMN1 already has values like '&gt;=3','&gt;=2','&gt;=1' . What is the reason behind this? and how can i update the column with '&gt;=2' ?</p>
