Connect to DB2 Data from PowerBuilder


This article demonstrates how to access DB2 data from PowerBuilder using the DB2 JDBC Driver.

The CData JDBC Driver for DB2 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 DB2 in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for DB2 to perform reads and writes.

Connect to DB2 Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for DB2. 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.db2.DB2Driver
    • URL: Enter the JDBC URL.

      Set the following properties to connect to DB2:

      • Server: Set this to the name of the server running DB2.
      • Port: Set this to the port the DB2 server is listening on.
      • Database: Set this to the name of the DB2 database.
      • User: Set this to the username of a user allowed to access the database.
      • Password: Set this to the password of a user allowed to access the database.

      You will also need to install the corresponding DB2 driver:

      • Windows: Install the IBM Data Server Provider for .NET.

        On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

      • Java: Install the IBM Data Server Driver for JDBC.

        In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the DB2 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.db2.jar

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

      jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using DB2 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 DB2 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.db2.DB2Driver',URL='jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;"; CONNECT USING SQLCA; dw_orders.SetTransObject(SQLCA); dw_orders.Retrieve();
