title: How to log SQL queries to a log file with CakePHP
body: <p>I have a CakePHP 1.2 application that makes a number of AJAX calls using the AjaxHelper object.  The AjaxHelper makes a call to a controller function which then returns some data back to the page.</p>
  
  <p>I would like to log the SQL queries that are executed by the AJAX controller functions.  Normally, I would just turn the debug level to 2 in config/core.php, however, this breaks my AJAX functionality because it causes the output SQL queries to be appended to the output that is returned to the client side.</p>
  
  <p>To get around this issue, I would like to be able to log any SQL queries performed to a log file.  Any suggestions?</p>
