title: MySQL query to insert an x before every value in column
body: <p>I have a MySQL table and want to add 'x' to the beginning of a column value for every row.</p>
  
  <p>My syntax guess was:</p>
  
  <pre><code>UPDATE table1 SET col5='x'.col5
  </code></pre>
  
  <p>This did not work. Any ideas?</p>
