Connect to Azure Table Data from PowerBuilder


This article demonstrates how to access Azure Table data from PowerBuilder using the Azure Table JDBC Driver.

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

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Azure Table to perform reads and writes.

Connect to Azure Table Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Azure Table. 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.azuretables.AzureTablesDriver
    • URL: Enter the JDBC URL.

      Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Table JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.azuretables.jar

      Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

      jdbc:azuretables:AccessKey=myAccessKey;Account=myAccountName;
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Azure Table 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 Azure Table 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.azuretables.AzureTablesDriver',URL='jdbc:azuretables:AccessKey=myAccessKey;Account=myAccountName;"; CONNECT USING SQLCA; dw_northwindproducts.SetTransObject(SQLCA); dw_northwindproducts.Retrieve();
