Natively Connect to IBM Cloud Data Engine Data in PHP


The CData ODBC driver for IBM Cloud Data Engine enables you to create PHP applications with connectivity to IBM Cloud Data Engine data. Leverage the native support for ODBC in PHP.

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

IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Establish a Connection

Open the connection to IBM Cloud Data Engine by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC IBMCloudDataEngine 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.

$conn = odbc_pconnect("CData ODBC IBMCloudDataEngine Source","user","password"); ... odbc_close($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 Jobs WHERE UserId = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC IBMCloudDataEngine Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Jobs WHERE UserId = ?"); $success = odbc_execute($query, array('[email protected]'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC IBMCloudDataEngine Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Status FROM Jobs WHERE UserId = [email protected]");

Process Results

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

$conn = odbc_connect("CData ODBC IBM Cloud Data Engine data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Status FROM Jobs WHERE UserId = [email protected]"); 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 IBM Cloud Data Engine data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Jobs WHERE UserId = ?"); $success = odbc_execute($query, array('[email protected]')); 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 IBM Cloud Data Engine-specific adaptations of the PHP community documentation for all ODBC functions.
