yii2中的case casetive query

要在yii2中查找记录,我使用以下代码:

$response = Response::findOne(['unique_url' => $unique_url]);

但$unique_url无论如何,它都会回归记录.如何做案例感慨？

我想你应该用 LIKE BINARY

为此你应该扩展你在查询条件中添加子句的modelSearch

public function search($params)
{
    $query = YuorModel::find();      
    .......
    .......

    $query->andFilterWhere(['like binary', 'unique_url', $this->unique_url])
          ->andFilterWhere(['like', 'your_field2', $this->your_field2])
    .......
