Connect to Amazon S3 Data from PowerBuilder via ODBC

The CData ODBC Driver for Amazon S3 can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to Amazon S3 data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to Amazon S3 as an ODBC Data Source

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.

To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

Create a Profile for the ODBC Driver for Amazon S3

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 S3. In the Database Painter, you can use wizards and the UI to work with Amazon S3 data.

1. In PowerBuilder, click Tools -> Database Painter.
2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
3. On the Connection tab, enter a name for the profile and select the Amazon S3 DSN in the Data Source menu. 👁 The ODBC DSN, required to create the Database Profile. (Salesforce is shown.)
   
4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Amazon S3 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 S3 data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC"
SQLCA.DBParm = "ConnectString='DSN=CData AmazonS3 Source'"
CONNECT USING SQLCA;
dw_objectsacl.SetTransObject(SQLCA);
dw_objectsacl.Retrieve();
