CakePHP - get last query run

I want to get the last query CakePHP ran. I can't turn debug on in core.php and I can't run the code locally. I need a way to get the last sql query and log it to the error log without effecting the live site. This query is failing but is being run.

something like this would be great:

$this->log($this->ModelName->lastQuery);

Thanks in advance.

For Cake 2.0, the query log is protected so this will work

function getLastQuery() {
  $dbo = $this->getDatasource();
  $logs = $dbo->getLog();
  $lastLog = end($logs['log']);
  return $lastLog['query'];
}

Tested in CakePHP v2.3.2

$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);
