[![Latest Unstable Version](https://poser.pugx.org/cooperl/laravel-db2/v/unstable)](https://packagist.org/packages/cooperl/laravel-db2)
[![License](https://poser.pugx.org/cooperl/laravel-db2/license)](https://packagist.org/packages/cooperl/laravel-db2)
laravel-db2 is a simple DB2 service provider for Laravel.
It provides DB2 Connection by extending the Illuminate Database component of the laravel framework.

- [Installation](#installation)
- [Registering the Package](#registering-the-package)
- [Configuration](#configuration)
- [Usage](#usage)
## Installation
Add laravel-db2 to your composer.json file:
```
"require": {
"cooperl/laravel-db2": "~1.0"
}
```
Use [composer](http://getcomposer.org) to install this package.
```
$ composer update
```
### Registering the Package
Add the laravel-db2 Service Provider to your config in ``app/config/app.php``:
```php
'providers' => [
'Cooperl\Database\DB2\DB2ServiceProvider'
],
```
### Configuration
There are two ways to configure laravel-db2. You can choose the most convenient way for you. You can put your DB2 credentials into ``app/config/database.php`` (option 1) file or use package config file which you can be generated through command line by artisan (option 2).
#### Option 1: Configure DB2 using ``app/config/database.php`` file
Simply add this code at the end of your ``app/config/database.php`` file:
```php
/*
|--------------------------------------------------------------------------
| DB2 Databases
|--------------------------------------------------------------------------
*/
'odbc' => [
'driver' => 'odbc',
'host' => '',
'database' => '',
'username' => '',
'password' => '',
'charset' => 'utf8',
'ccsid' => 1208,
'prefix' => '',
'schema' => '',
'i5_libl' => '',
'i5_lib' => '',
'i5_commit' => 0,
'i5_naming' => 0,
'i5_date_fmt' => 5,
'i5_date_sep' => 0,
'i5_decimal_sep' => 0,
'i5_time_fmt' => 0,
'i5_time_sep' => 0,
'options' => [
PDO::ATTR_CASE => PDO::CASE_LOWER,
PDO::ATTR_EMULATE_PREPARES => false,
PDO::ATTR_PERSISTENT => false
]
],
'ibm' => [
'driver' => 'ibm',
'host' => '',
'database' => '',
'username' => '',
'password' => '',
'charset' => 'utf8',
'ccsid' => 1208,
'prefix' => '',
'schema' => '',
'i5_libl' => '',
'i5_lib' => '',
'i5_commit' => 0,
'i5_naming' => 0,
'i5_date_fmt' => 5,
'i5_date_sep' => 0,
'i5_decimal_sep' => 0,
'i5_time_fmt' => 0,
'i5_time_sep' => 0,
'options' => [
PDO::ATTR_CASE => PDO::CASE_LOWER,
PDO::ATTR_EMULATE_PREPARES => false,
PDO::ATTR_PERSISTENT => false
]
],
```
driver setting is either 'odbc' for ODBC connection or 'ibm' for pdo_ibm connection
Then if driver is 'odbc', database must be set to ODBC connection name.
if driver is 'ibm', database must be set to IBMi database name (WRKRDBDIRE).
#### Option 2: Configure DB2 using package config file
Run on the command line from the root of your project:
```
$ php artisan config:publish cooperl/laravel-db2
```
Set your laravel-db2 credentials in ``app/config/packages/cooperl/laravel-db2/config.php``
the same way as above
## Usage
Consult the [Laravel framework documentation](http://laravel.com/docs).
