Natively Connect to SAP HANA Data in PHP

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

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

Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

Establish a Connection

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

$conn = odbc_connect("CData ODBC SAPHANA 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.

$conn = odbc_pconnect("CData ODBC SAPHANA Source","user","password"); ... odbc_close($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 Buckets WHERE Name = ?");

Execute Queries

Execute prepared statements with odbc_execute.

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

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC SAPHANA Source","user","password"); $query = odbc_exec($conn, "SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'");

Process Results

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

$conn = odbc_connect("CData ODBC SAP HANA data Source","user","password"); $query = odbc_exec($conn, "SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'"); 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 SAP HANA data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Buckets WHERE Name = ?"); $success = odbc_execute($query, array('TestBucket')); 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 HANA-specific adaptations of the PHP community documentation for all ODBC functions.
