Yii CDbCriteria 常用方法

Yii CDbCriteria 常用方法

    $criteria = new CDbCriteria;      
//函数方式
    $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 (1,23,,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('name', '分类');//搜索条件,其实代表了。。where name like '%分类%'  
    $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,  
                                    //即如果第二个参数是数组就会调用addInCondition  
 
    $criteria->addCondition("id = :id");  
    $criteria->params[':id']=1;  
 
//属性方式  
    $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->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

相关实例代码:

$criteria = new CDbCriteria();
$criteria->select = 'table_name,model_id,sum(amount) total';
$criteria->group = 'table_name,model_id';
$criteria->addCondition("$nIdcId=4");//也可以$criteria->condition = "$nIdcId=4";
$aResult = accessory_info::model()->findAll($criteria);
 
 
$c = new CDbCriteria();
$c->select = 't.id, t.created_at, t.outsource_id, t.user_id, t.operate, t.content';
$c->join = 'LEFT JOIN outsource ON outsource.id=t.outsource_id';
$c->condition = 'outsource.idc_id IN(' . implode(',', $idc_ids)  . ')';
 
if($last_log_id) {
	$c->condition .= " AND t.id > $last_log_id";
}
 
$c->limit = 20;
$c->order = 't.id DESC';
 
$logs = OutsourceProcessLog::model()->findAll($c);
