以下是CDbCriteria的一些用法
$criteria = new CDbCriteria; $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 /** * 传递变量 */ $criteria->addCondition("id = :id"); $criteria->params[‘:id‘]=1; /** * 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->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
CommandBuilder
$schema=Yii::app()->db->schema; $builder=$schema->commandBuilder; $command=$builder->createFindCommand($schema->getTable($tableName), $criteria);
Query Builder
$command = Yii::app()->getDb()->createCommand(); $command->select(‘name, label, controller,action‘)->from(‘{{menu_item}}‘); $command->where(‘menu_id=:mid ‘, array(‘:pid‘ => $parent_id); $command->order(‘sort_order ASC, label ASC‘); $results = $command->queryAll();
推荐compare,搜索条件允许为空因此不需要加条件
$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);
DAO
$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%"));
