How to execute custom query in cakephp 3.x

Custom query execution in cakephp. I have applied below code.

$conn = ConnectionManager::get('default');

$rs = $conn->query('SELECT * FROM customers');

It gives me blank array though customers table has 20 records.

Please suggest me some solution.

Thanks.

It's not recommended but somtimes there is no other way! :

You should mention namespace of connection manger
```
use Cake\Datasource\ConnectionManager;
```

Get/initialize a connection

$conn = ConnectionManager::get('default');

Execute SQL with something like this

$stmt = $conn->execute('SELECT * FROM customers');
