Connect to Redshift Data from PowerBuilder

This article demonstrates how to access Redshift data from PowerBuilder using the CData ODBC Driver for Redshift.

The CData JDBC Driver for Redshift is a standards-based control that can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to use the CData JDBC Driver for Redshift in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Redshift to perform CRUD operations (create, read, update, and delete).

Connect to Redshift Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Redshift. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

  1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

    Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

  2. Click Tools -> Database Painter.
  3. Right-click the JDBC node and click New Profile.
  4. In the Database Profile Setup dialog, enter the following:
    • Profile Name: Enter a user-friendly name for the profile.
    • Driver Name: Enter the class name of the driver, cdata.jdbc.redshift.RedshiftDriver
    • URL: Enter the JDBC URL. For example: jdbc:redshift:User=admin;Password=admin;Database=dev;Server=examplecluster.my.us-west-2.redshift.amazonaws.com;Port=5439;

    Redshift への接続には次を設定します:

    • Server: 接続するデータベースをホストしているクラスタのホスト名およびIP アドレス。
    • Port: クラスタのポート。
    • Database: データベース名、ブランクの場合ユーザーのデフォルトデータベースになります。
    • User: ユーザー名。
    • Password: ユーザーのパスワード。

    Server およびPort の値はAWS の管理コンソールで取得可能です:

    1. Amazon Redshift console (http://console.aws.amazon.com/redshift) を開く。
    2. Clusters ページで、クラスタ名をクリック。
    3. クラスタのConfiguration タブで、表示された接続文字列からクラスタのURL をコピーします。
    4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

    Using Redshift Data with PowerBuilder Controls

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

    SQLCA.DBMS = "JDBC" SQLCA.AutoCommit = False SQLCA.DBParm = "Driver='cdata.jdbc.redshift.RedshiftDriver',URL='jdbc:redshift:User=admin;Password=admin;Database=dev;Server=examplecluster.my.us-west-2.redshift.amazonaws.com;Port=5439;"; CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
