Natively Connect to SAP Business Warehouse Data in PHP

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

To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

The driver supports the following authentication schemes via the AuthScheme property:

• None: Anonymous authentication, if available on the server.
• Basic: Set User and Password and set AuthScheme to Basic.
• Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Establish a Connection

Open the connection to SAP Business Warehouse by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC SAPBusinessWarehouse 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.

$conn = odbc_pconnect("CData ODBC SAPBusinessWarehouse Source","user","password");
...
odbc_close($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 Sales WHERE Country = ?");

Execute Queries

Execute prepared statements with odbc_execute.

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

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC SAPBusinessWarehouse Source","user","password");
$query = odbc_exec($conn, "SELECT CustomerCount, City FROM Sales WHERE Country = 'US'");
  

Process Results

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

$conn = odbc_connect("CData ODBC SAP Business Warehouse data Source","user","password");
$query = odbc_exec($conn, "SELECT CustomerCount, City FROM Sales WHERE Country = 'US'");
while($row = odbc_fetch_array($query)){
 echo $row["CustomerCount"] . "\n";
}

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

$conn = odbc_connect("CData ODBC SAP Business Warehouse data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Sales WHERE Country = ?");
$success = odbc_execute($query, array('US'));
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 SAP Business Warehouse-specific adaptations of the PHP community documentation for all ODBC functions.
