Natively Connect to Oracle Eloqua Reporting Data in PHP

Drop the CData ODBC Driver for Oracle Eloqua Reporting into your LAMP or WAMP stack to build Oracle Eloqua Reporting-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Oracle Eloqua Reporting data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Oracle Eloqua Reporting supports the following authentication methods:

• Basic authentication (User and Password)
• OAuth 2.0 code grant flow
• OAuth 2.0 password grant flow

Basic Authentication (User and Password)

To perform authentication with a user and password, specify these properties:

• AuthScheme: Basic.
• Company: The company name associated with your Oracle Eloqua Reporting account.
• User: Your login account name.
• Password: Your login password.

OAuth Authentication (Code Grant Flow)

To authenticate with the OAuth code grant flow, you must set AuthScheme to OAuth and create a custom OAuth application. For information about how to create a custom OAuth application, see the Help documentation.

Then set the following properties:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret that was assigned when you registered your application.
• CallbackURL: The redirect URI that was defined when you registered your application.

When you connect, the driver opens Oracle Eloqua Reporting's OAuth endpoint in your default browser. Log in and grant permissions to the application. When the access token expires, the driver refreshes it automatically.

OAuth Authentication (Password Grant Flow)

With the OAuth password grant flow, you can use your OAuth application's credentials alongside your user credentials to authenticate without the need to grant permission manually via a browser prompt. You must create an OAuth app (see the Help documentation) to use this authentication method.

Set the following properties:

• AuthScheme: OAuthPassword
• Company: The company's unique identifier.
• User: Your login account name.
• Password: Your login password.
• OAuthClientId: The client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Establish a Connection

Open the connection to Oracle Eloqua Reporting by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC OracleEloquaReporting Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC OracleEloquaReporting Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM WHERE = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC OracleEloquaReporting Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM WHERE = ?");
$success = odbc_execute($query, array(''));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC OracleEloquaReporting Source","user","password");
$query = odbc_exec($conn, "SELECT , FROM WHERE = ''");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC Oracle Eloqua Reporting data Source","user","password");
$query = odbc_exec($conn, "SELECT , FROM WHERE = ''");
while($row = odbc_fetch_array($query)){
 echo $row[""] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC Oracle Eloqua Reporting data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM WHERE = ?");
$success = odbc_execute($query, array(''));
if($success)
 odbc_result_all($query);

More Example Queries

You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Oracle Eloqua Reporting-specific adaptations of the PHP community documentation for all ODBC functions.
