Natively Connect to Oracle Eloqua Data in PHP

The CData ODBC driver for Oracle Eloqua enables you to create PHP applications with connectivity to Oracle Eloqua data. Leverage the native support for ODBC in PHP.

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

There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

Establish a Connection

Open the connection to Oracle Eloqua by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

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

Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect 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.

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

Create Prepared Statements

Create prepared statements and parameterized queries with the odbc_prepare function.

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

Execute Queries

Execute prepared statements with odbc_execute.

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

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC OracleEloqua Source","user","password"); $query = odbc_exec($conn, "SELECT Name, ActualCost FROM Campaign");

Process Results

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

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

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

$conn = odbc_connect("CData ODBC Oracle Eloqua data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Campaign WHERE ShipCity = ?"); $success = odbc_execute($query, array('New York')); 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-specific adaptations of the PHP community documentation for all ODBC functions.
