ServiceNow ODBC Driver

The ServiceNow ODBC Driver is a powerful tool that allows you to connect with live ServiceNow data, directly from any applications that support ODBC connectivity.

Access ServiceNow data like you would a database - read, write, and update Schedules, Timelines, Questions, Syslogs, etc. through a standard ODBC Driver interface.



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

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

Connect to ServiceNow 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.

ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

Create a Profile for the ODBC Driver for ServiceNow

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

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

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