Connect to Xero Data from PowerBuilder via JDBC

The CData JDBC driver for Xero 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 Xero in PowerBuilder.

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

Getting Started

Connect to Xero Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Xero. 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.xero.XeroDriver
   • URL: Enter the JDBC URL.

     To connect, set the Schema connection property in addition to any authentication values. Xero offers authentication for private applications, public applications, and partner applications. Set the XeroAppAuthentication property to PUBLIC, PRIVATE, or PARTNER, depending on the type of application configured. To connect from a private application, you will additionally need to set the OAuthAccessToken, OAuthClientId, OAuthClientSecret, CertificateStoreType, CertificateStore, and CertificateStorePassword.

     To connect from a public or partner application, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL, or you can register an app to obtain your own OAuth values.

     See the "Getting Started" chapter of the help documentation for a guide to authenticating to Xero.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.xero.jar
     

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

     jdbc:xero:InitiateOAuth=GETANDREFRESH;

   👁 The JDBC data source defined in the Database Profile Setup dialog. (Salesforce is shown.)
   
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Xero 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 Xero 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.xero.XeroDriver',URL='jdbc:xero:InitiateOAuth=GETANDREFRESH;";
CONNECT USING SQLCA;
dw_items.SetTransObject(SQLCA);
dw_items.Retrieve();
