Natively Connect to IBM Cloud SQL Query Data in PHP

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

Drop the CData ODBC Driver for IBM Cloud SQL Query into your LAMP or WAMP stack to build IBM Cloud SQL Query-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to IBM Cloud SQL Query 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 SQL 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 SQL Query by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC IBMCloudSQLQuery 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.

$conn = odbc_pconnect("CData ODBC IBMCloudSQLQuery Source","user","password"); ... odbc_close($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 IBMCloudSQLQuery Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Jobs WHERE UserId = ?"); $success = odbc_execute($query, array('user@domain.com'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC IBMCloudSQLQuery Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Status FROM Jobs WHERE UserId = user@domain.com");

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 SQL Query data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Status FROM Jobs WHERE UserId = user@domain.com"); 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 SQL Query data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Jobs WHERE UserId = ?"); $success = odbc_execute($query, array('user@domain.com')); 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 SQL Query-specific adaptations of the PHP community documentation for all ODBC functions.
