Yii CDbCriteria常用用法

$criteria = new CDbCriteria;$criteria->compare('name',$this->name,true,'OR'); //like部分匹配//$criteria->addCondition("id=1"); //查询条件，即where id = 1//$criteria->addInCondition('id', array(1,2,3,4,5)); //代表where id IN (1,2,3,4,5);$criteria->compare('name', array(1,2,3,4,5));$criteria->addNotInCondition('id', array(1,2,3,4,5));//与上面正好相法，是NOT IN//$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//$criteria->addSearchCondition('name', '分类');//搜索条件，其实代表了。where name like '%分类%'$criteria->compare("id","<>1"); //not like$criteria->addBetweenCondition('id', 1, 4);//between 1 and 4$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，$criteria->compare("id","<1"); //这个方法他会根据你提供的条件进行判断//即如果第二个参数是数组就会调用addInCondition

$criteria = new CDbCriteria;$criteria->alias = 't';  //table t，默认select='*';//一些public vars $criteria->select = 'id,parentid,name'; //代表了要查询的字段，默认select='*';  $criteria->join = 'xxx'; //连接表  $criteria->with = 'xxx'; //调用relations   $criteria->with = array('accounts','varchar');$criteria->with  = array('teacher'=>array('select'=>'username,company_id', 'order'=>'teacher.username ASC'));$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 = 'xxx DESC,XXX ASC' ;//排序条件  $criteria->group = 'group 条件';  $criteria->having = 'having 条件 ';  $criteria->distinct = FALSE; //是否唯一查询Article::model()->findAll($criteria);

$sql ='  ...  yiiblog_desc like :keywords or yiiblog_title like :keywords ... ';$TmpStatement = Yii::app()->db->createCommand($sql);$TmpStatement->bindValue(':keywords', '%'.$keywords.'%');findAll('username?like?:username?'?,array(":username"=>"%$key%"));
