Connect to Redshift Data from PowerBuilder

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

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

Create a Profile for the ODBC Driver for Redshift

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. In the Database Painter, you can use wizards and the UI to work with Redshift data.

  1. If you have not already done so, create an ODBC DSN for Redshift. The DSN contains the connection properties required to connect to Redshift 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:
    • User
    • Password
    • Database
    • Server
    • Port

    To connect to Redshift, set the following:

    • Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
    • Port: Set this to the port of the cluster.
    • Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
    • User: Set this to the username you want to use to authenticate to the Server.
    • Password: Set this to the password you want to use to authenticate to the Server.

    You can obtain the Server and Port values in the AWS Management Console:

    1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
    2. On the Clusters page, click the name of the cluster.
    3. On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.
    See the help documentation for a guide to creating a Redshift 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 Redshift DSN in the Data Source menu.
  5. 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 ODBC 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 = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Redshift Source'" CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
