Yii的Active Recorder包装了很多。
特别是把SQL中 把where,order,limit,IN/not IN,like等常用短句都包含进CDbCriteria这个类中去,这样整个代码会比较规范,一目了然。
$criteria =newCDbCriteria;
$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);//between1 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;
$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 offset1,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
find里面是可以使用CDbCriteria类来进行各种sql的操作的,具体的用法可以参考文档。
blog.csdn.net/...973922 这个地方也有很多数据库相关的操作的解释,非常详细,内容也很全。
如果只是需要选取特定的字段,可以使用如下的方法
model()->find(array('select' => '字段名1,字段名2', 'condition' => '选取条件'))
findAll类似
不知道你的需求是什么,为什么一定要用现成的组件呢,你试下,
$sql = "call fun()";
$data = Yii::app()->db->createCommand($sql)->queryAll();
