yii2 の andWhere と andFilterWhere の違い

#andWhere()
 
//定义一个不为空的参数
$name = 'lisi';
$query = Model::find();
$query->andWhere(['name'=>$name]);
//生成的语句
SELECT * FROM `table_name` WHERE `name`='lisi'
 
//定义一个为空的参数
$name = '';
$query->andWhere(['name'=>$name]);
//生成的语句
SELECT * FROM `table_name` WHERE `name`=''
 
#andFilterWhere
 
//定义一个不为空的参数
$name = 'lisi';
$query = Model::find();
$query->andFilterWhere(['name'=>$name]);
//生成的语句
SELECT * FROM `table_name` WHERE `name`='lisi'
 
//定义一个为空的参数
$name = '';
$query->andFilterWhere(['name'=>$name]);
//生成的语句
SELECT * FROM `table_name`
