本文实例总结了一些Yii的CDbCriteria查询条件用法,分享给大家供大家参考。具体分析如下:

这里就是Yii中使用CDbCriteria方法来进行查询的各种条件:

代码如下:

$criteria = new CDbCriteria;
$criteria->addCondition("MACID=464"); //查询条件,即where id = 1
$criteria->addInCondition('id', array(1,2,3,4,5)); //代表where id IN (1,23,,4,5,);
$criteria->addNotInCondition('id', array(1,2,3,4,5));//与上面正好相法,是NOT IN
$criteria->addCondition('id=1','OR');//这是OR条件,多个条件的时候,该条件是OR而非AND
$criteria->addSearchCondition('link', '裸体');//搜索条件where name like '%分类%'
$criteria->addBetweenCondition('id', 10000, 10005);//between 10000 and 10005

$criteria->compare('id', 1);  //这个方法比较特殊,他会根据你的参数
//自动处理成addCondition或者addInCondition,
//即如果第二个参数是数组就会调用addInCondition 
/**
* 传递变量
*/ 
$criteria->addCondition("id = :id"); 
$criteria->params[':id']=10; 
/**
* 一些public vars
*/ 
$criteria->select = 'id,MACID,type'; //代表了要查询的字段,默认select='*';
$criteria->join = 'xxx'; //连接表
$criteria->with = 'xxx'; //调用relations
$criteria->limit = 10;    //取1条数据,如果小于0,则不作处理
$criteria->offset = 1;   //两条合并起来,则表示 limit 10 offset 1,或者代表了。limit 1,10
$criteria->order = 'id DESC,MACID ASC' ;//排序条件
$criteria->group = 'group type';
$criteria->having = 'having 条件 ';
$criteria->distinct = FALSE; //是否唯一查询 
return new CActiveDataProvider('visitlog', array(
  'criteria'=>$criteria,
));

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
