Connect to EnterpriseDB Data from PowerBuilder

The CData JDBC Driver for EnterpriseDB 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 EnterpriseDB in PowerBuilder.

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

Connect to EnterpriseDB Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for EnterpriseDB. 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.enterprisedb.EnterpriseDBDriver
   • URL: Enter the JDBC URL.

     The following connection properties are required in order to connect to data.

     • Server: The host name or IP of the server hosting the EnterpriseDB database.
     • Port: The port of the server hosting the EnterpriseDB database.

     You can also optionally set the following:

     • Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

     Connect Using Standard Authentication

     To authenticate using standard authentication, set the following:

     • User: The user which will be used to authenticate with the EnterpriseDB server.
     • Password: The password which will be used to authenticate with the EnterpriseDB server.

     Connect Using SSL Authentication

     You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

     • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
     • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
     • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
     • SSLClientCertType: The certificate type of the client store.
     • SSLServerCert: The certificate to be accepted from the server.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.enterprisedb.jar

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

     jdbc:enterprisedb:User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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