Connect to Amazon DynamoDB Data from PowerBuilder





Amazon DynamoDB ODBC Driver

Amazon DynamoDB ODBC ドライバーは、ODBC 接続をサポートする任意のアプリケーションからリアルタイムなAmazon DynamoDB NoSQL データベースデータに直接接続できるパワフルなツールです。標準のODBC ドライバーインターフェースを使用して、データベースのようにDynamoDB データにアクセスし、NoSQL テーブルの読み、書き、更新を実行できます。



This article demonstrates how to use the CData ODBC Driver for Amazon DynamoDB to connect to Amazon DynamoDB data and execute queries in PowerBuilder.

The CData ODBC Driver for Amazon DynamoDB can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to connect to Amazon DynamoDB data and execute queries from the Database Painter and controls such as the DataWindow.


Create a Profile for the ODBC Driver for Amazon DynamoDB

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Amazon DynamoDB. In the Database Painter, you can use wizards and the UI to work with Amazon DynamoDB data.

  1. If you have not already done so, create an ODBC DSN for Amazon DynamoDB. The DSN contains the connection properties required to connect to Amazon DynamoDB data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • Access Key
    • Secret Key
    • Domain
    • Region

    Amazon DynamoDB への接続には、AccessKey、SecretKey、オプションでDomain とRegion を設定します。 AWS サービスアカウントのセキュリティクレデンシャルページでAccessKey とSecretKey を取得できます。 Region は、DynamoDB にログインしている時の左上に表示されています。

    See the help documentation for a guide to creating a Amazon DynamoDB DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the Amazon DynamoDB DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Amazon DynamoDB Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Amazon DynamoDB data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Amazon DynamoDB Source'" CONNECT USING SQLCA; dw_lead.SetTransObject(SQLCA); dw_lead.Retrieve();
