Connect to Greenhouse Data from PowerBuilder


This article demonstrates how to use the CData ODBC Driver for Greenhouse to connect to Greenhouse data and execute queries in PowerBuilder.

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

Connect to Greenhouse 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.

You need an API key to connect to Greenhouse. To create an API key, follow the steps below:

  1. Click the Configure icon in the navigation bar and locate Dev Center on the left.
  2. Select API Credential Management.
  3. Click Create New API Key.
    • Set "API Type" to Harvest.
    • Set "Partner" to custom.
    • Optionally, provide a description.
  4. Proceed to Manage permissions and select the appropriate permissions based on the resources you want to access through the driver.
  5. Copy the created key and set APIKey to that value.

Create a Profile for the ODBC Driver for Greenhouse

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Greenhouse. In the Database Painter, you can use wizards and the UI to work with Greenhouse 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 Greenhouse DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

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