Amazon DynamoDB Icon Amazon DynamoDB ODBC Driver

The Amazon DynamoDB ODBC Driver is a powerful tool that allows you to connect with live data from Amazon DynamoDB NoSQL database, directly from any applications that support ODBC connectivity.

Access DynamoDB data like you would a database - read, write, and update NoSQL tables through a standard ODBC Driver interface.

Natively Connect to Amazon DynamoDB Data in PHP


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

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

The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

Establish a Connection

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

$conn = odbc_connect("CData ODBC AmazonDynamoDB 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.

$conn = odbc_pconnect("CData ODBC AmazonDynamoDB Source","user","password"); ... odbc_close($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 Lead WHERE FirstName = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC AmazonDynamoDB Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Lead WHERE FirstName = ?"); $success = odbc_execute($query, array('Bob'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC AmazonDynamoDB Source","user","password"); $query = odbc_exec($conn, "SELECT Industry, Revenue FROM Lead");

Process Results

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

$conn = odbc_connect("CData ODBC Amazon DynamoDB data Source","user","password"); $query = odbc_exec($conn, "SELECT Industry, Revenue FROM Lead"); while($row = odbc_fetch_array($query)){ echo $row["Industry"] . "\n"; }

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

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