如何在cakephp 3.x中执行自定义查询

Question

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! :

1. You should mention namespace of connection manger

    use Cake\\Datasource\\ConnectionManager; 

2. Get/initialize a connection

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

3. Execute SQL with something like this

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

4. Fetch the results

    $results = $stmt ->fetchAll('assoc');
