title: is it possible to update an existing row in DB, using liquibase?
body: <p>Tried to find an answer to this question, but couldn't.</p>
  
  <p>So, for example I have this table:</p>
  
  <p><strong>TABLE:</strong></p>
  
  <pre><code>col1 | col2
  123       0
  124       1
  </code></pre>
  
  <p>and I want to change col2 value to 1 and this is how I'm trying to do it:</p>
  
  <pre><code>&lt;changeSet author="myName" id="7799"&gt;
          &lt;sql&gt;
          UPDATE TABLENAME;
          SET COL1='1' WHERE col1='123';
          &lt;/sql&gt;
  &lt;/changeSet&gt;
  </code></pre>
  
  <p>Alas, it doesn't work. So, I was wondering if it is even possible to do that with liquibase? Since, most tags in the documentation have to do with creating table, adding columns etc.</p>
