Access SAP Ariba Procurement Data from MySQL in PHP

You can use the CData SQL Gateway and ODBC Driver for SAP Ariba Procurement to access SAP Ariba Procurement data from MySQL clients, without needing to perform an ETL or cache data. Follow the steps below to connect to SAP Ariba Procurement data in real time through PHP's standard MySQL interfaces, mysqli and PDO_MySQL.

Connect to SAP Ariba Procurement Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

In order to connect with SAP Ariba Procurement, set the following:

• ANID: Your Ariba Network ID.
• ANID: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Buyer or Supplier API based on your business role (possible values are PurchaseOrdersBuyerAPIV1 or PurchaseOrdersSupplierAPIV1).
• Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

Authenticating with OAuth

After setting connection properties, you need to configure OAuth connectivity to authenticate.

• Set AuthScheme to OAuthClient.
• Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

  For more information on creating an OAuth application, refer to the Help documentation.

Automatic OAuth

After setting the following, you are ready to connect:

APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

When you connect, the provider automatically completes the OAuth process:

1. The provider obtains an access token from SAP Ariba and uses it to request data.
2. The provider refreshes the access token automatically when it expires.
3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to SAP Ariba Procurement data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Connect in PHP

The following examples show how to use object-oriented interfaces to connect and execute queries. Initialize the connection object with the following parameters to connect to the virtual MySQL database:

• Host: Specify the remote host location where the service is running. In this case "localhost" is used for the remote host setting since the service is running on the local machine.
• Username: Specify the username for a user you authorized on the SQL Gateway's Users tab.
• Password: Specify the password for the authorized user account.
• Database Name: Specify the system DSN as the database name.
• Port: Specify the port the service is running on; port 3306 in this example.

mysqli

<?php
$mysqli = new mysqli("localhost", "user", "password", "CData SAPAribaProcurement Sys","3306");
?>

PDO

<?php
$pdo = new PDO('mysql:host=localhost;dbname=CData SAPAribaProcurement Sys;port=3306', 'user', 'password');
?>

Query in PHP

With the connection established, you can then access tables. The following steps walk through the example:

1. Query the table; for example, Orders. The results will be stored as an associative array in the $result object.
2. Iterate over each row and column, printing the values to display in the PHP page.
3. Close the connection.

mysqli

$result = $mysqli->query("SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'");
while($row = $result->fetch_assoc()) {
 foreach ($row as $k=>$v) {
 echo "$k : $v";
 echo "<br>"; 
 }
}
$mysqli->close();

PDO

$result = $pdo->query("SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
 foreach ($row as $k=>$v) {
 echo "$k : $v";
 echo "<br>"; 
 }
}
$result = null;
$pdo = null;
