Connecting Oracle

To configure Yii DB Oracle with DI container, you need to create config/common/di/db-oracle.php configuration file.

use Yiisoft\Db\Connection\ConnectionInterface;
use Yiisoft\Db\Oracle\Connection;
use Yiisoft\Db\Oracle\Driver;

/** @var array $params */

return [
    ConnectionInterface::class => [
        'class' => Connection::class,
        '__construct()' => [
            'driver' => new Driver(
                $params['yiisoft/db-oracle']['dsn'],
                $params['yiisoft/db-oracle']['username'],
                $params['yiisoft/db-oracle']['password'],
            ),
        ],
    ],
];

Create a file config/common/params.php for common parameters.

use Yiisoft\Db\Oracle\Dsn;

return [
    'yiisoft/db-oracle' => [
        'dsn' => (new Dsn('oci', 'localhost', 'XE', '1521', ['charset' => 'AL32UTF8']))->asString(),
        'username' => 'user',
        'password' => 'password',
    ],
];

To configure without DI container, you need to follow these steps:

use Yiisoft\Cache\ArrayCache;
use Yiisoft\Db\Cache\SchemaCache;
use Yiisoft\Db\Oracle\Connection;
use Yiisoft\Db\Oracle\Driver;
use Yiisoft\Db\Oracle\Dsn;

// Dsn.
$dsn = (new Dsn('oci', 'localhost', 'XE', '1521', ['charset' => 'AL32UTF8']))->asString();

// PSR-16 cache implementation.
$arrayCache = new ArrayCache();

// Schema cache.
$schemaCache = new SchemaCache($cache);

// PDO driver.
$pdoDriver = new Driver($dsn, 'user', 'password'); 

// Connection.
$db = new Connection($pdoDriver, $schemaCache);
