Doctrine OCI8 Driver

The Doctrine OCI8 driver with cursor support, for PHP >= 7.4.

This is a fork of the original package develpup/doctrine-oci8-extended from Jason Hofer.

Installation

composer require ecphp/doctrine-oci8

Configuration

Symfony 5

Use the ecphp/doctrine-oci8-bundle to automatically configure the parameters.

If you prefer modifying the configuration, edit the doctrine.yaml as such:

doctrine:
    dbal:
        driver_class: EcPhp\DoctrineOci8\Doctrine\DBAL\Driver\OCI8\Driver
        types:
            cursor:  EcPhp\DoctrineOci8\Doctrine\DBAL\Types\CursorType

Usage

<?php

namespace App;

use Doctrine\DBAL\Types\Type;
use EcPhp\DoctrineOci8\Doctrine\DBAL\Types\CursorType;
use EcPhp\DoctrineOci8\Doctrine\DBAL\Driver\OCI8\Driver;

include __DIR__ .'/vendor/autoload.php';

// Register the custom type.
if (false === Type::hasType('cursor')) {
    Type::addType('cursor', CursorType::class);
}

$config = new Doctrine\DBAL\Configuration();
$params = [
    'dbname'      => 'database_sid',
    'user'        => 'database_username',
    'password'    => 'database_password',
    'host'        => 'database.host',
    'port'        => 1521,
    'persistent'  => true,
    'driverClass' => Driver::class, // This is where we load the driver.
];
$conn = Doctrine\DBAL\DriverManager::getConnection($params, $config);

$stmt = $conn->prepare('BEGIN MY_STORED_PROCEDURE(:user_id, :cursor); END;');
$stmt->bindValue('user_id', 42);
$stmt->bindParam('cursor', $cursor, \PDO::PARAM_STMT);
$stmt->execute();

/** @var $cursor EcPhp\DoctrineOci8\Doctrine\DBAL\Driver\OCI8\OCI8Cursor */
$cursor->execute();

while ($row = $cursor->fetch()) {
    print_r($row);
    echo PHP_EOL;
}

$cursor->closeCursor();
$stmt->closeCursor();

Types

For OCI8 types that are not represented by PDO::PARAM_ constants, pass OCI8::PARAM_ constants as the type argument of bindValue() and bindParam().

Cursors

Cursors can be specified as PDO::PARAM_STMT, OCI8::PARAM_CURSOR, or just 'cursor'. Only the bindParam() method can be used to bind a cursor to a statement.

Sub-Cursors

Cursor resources returned in a column of a result set are automatically fetched. You can change this behavior by passing in one of these fetch mode flags:

• OCI8::RETURN_RESOURCES to return the raw PHP resources.
• OCI8::RETURN_CURSORS to return the OCI8Cursor objects that have not yet been executed.

use Doctrine\DBAL\Driver\OCI8\OCI8;

$rows = $stmt->fetchAll(\PDO::FETCH_ASSOC+OCI8::RETURN_CURSORS);
$rows = $stmt->fetchAll(\PDO::FETCH_BOTH+OCI8::RETURN_RESOURCES);

Special thanks to Michal Tichý for his patch.

Tests

In order to have a working development environment, tests are Docker based.

To run the tests, do the following steps

1. cp .env.example .env
2. docker-compose up -d
3. docker-compose exec php ./vendor/bin/phpunit
4. CTRL+C
5. docker-compose down
