title: Is it possible to show only value in MySQL "show variables"?
body: <p>It is an easy task to find MySQL variable values:</p>
  
  <pre>
  mysql> show variables where Variable_name = 'version';
  +---------------+--------------------+
  | Variable_name | Value              |
  +---------------+--------------------+
  | version       | 5.0.19-Max         |
  +---------------+--------------------+
  1 row in set (0.00 sec)
  </pre>
  
  <p>But is there any syntax that allows to select only column with variable value, like so:</p>
  
  <pre>
  mysql> command_i_want_to_know
  +--------------------+
  | Value              |
  +--------------------+
  | 5.0.19-Max         |
  +--------------------+
  1 row in set (0.00 sec)
  </pre>
