1. CakePHP如何给查询时添加conditions，'!='要前置，
（1）数据库sql语句如下：
SELECT * FROM stat_clienttype WHERE stat_clienttype_name <> 'Not In Use';
（2）Controller里代码如下：
$statClientTypes = $this->StatClientType->find('list', array(
'fields'=>array('stat_clienttype_id','stat_clienttype_name'),
'conditions'=>array('stat_clienttype_name !=' => 'Not In Use'),
'order'=>'stat_clienttype_name',
'recursive'=>0
));
