###Laravel-OCI8
Laravel-OCI8 is an Oracle Database Driver package for Laravel. Laravel-OCI8 is an extension of Illuminate/Database that uses OCI8 extension to communicate with Oracle. Thanks to @taylorotwell.
The yajra/laravel-pdo-via-oci8 package is a simple userspace driver for PDO that uses the tried and tested OCI8 functions instead of using the still experimental and not all that functional PDO_OCI library.
Please report any bugs you may find.

###Requirements
- PHP >= 5.4
- PHP OCI8 extension
###Installation
{
"require": {
"yajra/laravel-oci8": "~2.0"
}
}
And then run composer update
Once Composer has installed or updated your packages you need to register the service provider. Open up app/config/app.php and find the providers key and add:
'yajra\Oci8\Oci8ServiceProvider'Then setup a valid database configuration using the driver oracle. Configure your connection as usual with:
'oracle' => array(
'driver' => 'oracle',
'host' => 'oracle.host',
'port' => '1521',
'database' => 'xe',
'username' => 'hr',
'password' => 'hr',
'charset' => 'AL32UTF8',
'prefix' => '',
)And run your laravel installation...
###Starter Kit To help you kickstart with Laravel, you may want to use the starter kit package below:
Starter kit package above were forked from brunogaspar/laravel4-starter-kit. No need to re-invent the wheel.
###Auto-Increment Support To support auto-increment in Laravel-OCI8, you must meet the following requirements:
- Table must have a corresponding sequence with this format
{$table}_{$column}_seq - Sequence next value are executed before the insert query.
Note: If you will use Laravel Migration feature, the required sequence and a trigger will automatically be created. Please also note that trigger, sequence and indexes name will be truncated to 30 chars when created via Schema Builder hence there might be cases where the naming convention would not be followed. I suggest that you limit your object name not to exceed 20 chars as the builder added some naming convention on it like _seq, _trg, _unique, etc...
Schema::create('posts', function($table)
{
$table->increments('id');
$table->string('title');
$table->string('slug');
$table->text('content');
$table->timestamps();
});This script will trigger Laravel-OCI8 to create the following DB objects
- posts (table)
- posts_id_seq (sequence)
- posts_id_trg (trigger)
###Auto-Increment Start With and No Cache Option
- You can now set the auto-increment starting value by setting the
startattribute. - If you want to disable cache, then add
nocacheattribute.
Schema::create('posts', function($table)
{
$table->increments('id')->start(10000)->nocache();
$table->string('title');
}####Inserting Records Into A Table With An Auto-Incrementing ID
$id = DB::connection('oracle')->table('users')->insertGetId(
array('email' => '[email protected]', 'votes' => 0), 'userid'
);Note: When using the insertGetId method, you can specify the auto-incrementing column name as the second parameter in insertGetId function. It will default to "id" if not specified.
###Oracle Blob Querying a blob field will now load the value instead of the OCI-Lob object.
$data = DB::table('mylobs')->get();
foreach ($data as $row) {
echo $row->blobdata . '<br>';
}Inserting a blob via transaction
DB::transaction(function($conn){
$pdo = $conn->getPdo();
$sql = "INSERT INTO mylobs (id, blobdata)
VALUES (mylobs_id_seq.nextval, EMPTY_BLOB())
RETURNING blobdata INTO :blob";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':blob', $lob, PDO::PARAM_LOB);
$stmt->execute();
$lob->save('blob content');
});Inserting Records Into A Table With Blob And Auto-Incrementing ID
$id = DB::table('mylobs')->insertLob(
array('name' => 'Insert Binary Test'),
array('blobfield'=>'Lorem ipsum Minim occaecat in velit.')
);Note: When using the insertLob method, you can specify the auto-incrementing column name as the third parameter in insertLob function. It will default to "id" if not specified.
Updating Records With A Blob
$id = DB::table('mylobs')->whereId(1)->updateLob(
array('name'=>'demo update blob'),
array('blobfield'=>'blob content here')
);Note: When using the insertLob method, you can specify the auto-incrementing column name as the third parameter in insertLob function. It will default to "id" if not specified.
###Updating Blob directly using OracleEloquent
On your model, just add use yajra\Oci8\Eloquent\OracleEloquent as Eloquent; and define the fields that are blob via protected $binaries = [];
Example Model:
use yajra\Oci8\Eloquent\OracleEloquent as Eloquent;
class Post extends Eloquent {
// define binary/blob fields
protected $binaries = ['content'];
// define the sequence name used for incrementing
// default value would be {table}_{primaryKey}_seq if not set
protected $sequence = null;
}Usage:
Route::post('save-post', function()
{
$post = new Post;
$post->title = Input::get('title');
$post->company_id = Auth::user()->company->id;
$post->slug = Str::slug(Input::get('title'));
// set binary field (content) value directly using model attribute
$post->content = Input::get('content');
$post->save();
});Limitation: Saving multiple records with a blob field like
Post::insert($posts)is not yet supported!
##Sequence
Oracle Sequence can be loaded via DB::getSequence().
$sequence = DB::getSequence();
// create a sequence
$sequence->create('seq_name');
// drop a sequence
$sequence->drop('seq_name');
// next value
$sequence->nextValue('seq_name');
// current value
$sequence->currentValue('seq_name');
$sequence->lastInsertId('seq_name');
// check if exists
$sequence->exists('seq_name');##Trigger
Oracle Trigger can be loaded via DB::getTrigger().
$trigger = DB::getTrigger();
// create an auto-increment trigger
$trigger->autoIncrement($table, $column, $triggerName, $sequenceName);
// drop a trigger
$trigger->drop($triggerName);###Date Formatting
(Note: Oracle's
DATE&TIMESTAMPformat is set toYYYY-MM-DD HH24:MI:SSby default to match PHP's common date format)
// set oracle session date and timestamp format
DB::setDateFormat('MM/DD/YYYY');###Support
Just like the built-in database drivers, you can use the connection method to access the oracle database(s) you setup in the database config file.
See Laravel Database Basic Docs for more information.
###Using the package outside of Laravel
- add
"yajra/laravel-oci8": "~2.0"on your composer then runcomposer install - create
database.phpand add the code below
require 'vendor/autoload.php';
use Illuminate\Database\Capsule\Manager as Capsule;
use yajra\Oci8\Connectors\OracleConnector;
use yajra\Oci8\Oci8Connection;
$capsule = new Capsule;
$manager = $capsule->getDatabaseManager();
$manager->extend('oracle', function($config)
{
$connector = new OracleConnector();
$connection = $connector->connect($config);
$db = new Oci8Connection($connection, $config["database"], $config["prefix"]);
// set oracle date format to match PHP's date
$db->setDateFormat('YYYY-MM-DD HH24:MI:SS');
return $db;
});
$capsule->addConnection(array(
'driver' => 'oracle',
'host' => 'oracle.host',
'database' => 'xe',
'username' => 'user',
'password' => 'password',
'prefix' => '',
'port' => 1521
));
$capsule->bootEloquent();// Set the event dispatcher used by Eloquent models... (optional)
use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;
$capsule->setEventDispatcher(new Dispatcher(new Container));
// Make this Capsule instance available globally via static methods... (optional)
$capsule->setAsGlobal();- Now we can start working with database tables just like we would if we were using Laravel!
include 'database.php';
// Create the User model
class User extends Illuminate\Database\Eloquent\Model {
public $timestamps = false;
}
// Grab a user with an id of 1
$user = User::find(1);
echo $user->toJson(); die();###License
