Natively Connect to SAP Fieldglass Data in PHP

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

Drop the CData ODBC Driver for SAP Fieldglass into your LAMP or WAMP stack to build SAP Fieldglass-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to SAP Fieldglass 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 authenticate, you will need to specify the Username, Password, APIKey, and EnvironmentURL connection properties.

To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.

Establish a Connection

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

$conn = odbc_connect("CData ODBC SAPFieldglass 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.

$conn = odbc_pconnect("CData ODBC SAPFieldglass Source","user","password"); ... odbc_close($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 AuditTrails WHERE Company = ?");

Execute Queries

Execute prepared statements with odbc_execute.

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

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC SAPFieldglass Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'");

Process Results

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

$conn = odbc_connect("CData ODBC SAP Fieldglass data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'"); while($row = odbc_fetch_array($query)){ echo $row["Id"] . "\n"; }

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

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