Connect to ServiceNow Data from PowerBuilder





ServiceNow ODBC Driver

ServiceNow ODBC Driver は、ODBC 接続をサポートするさまざまなアプリケーションからServiceNow のリアルタイムデータ連携を実現するパワフルなツールです。

データベースにアクセスするときと同感覚でServiceNow データにアクセスし、標準ODBC Driver インターフェースを通じてServiceNow に読み出し、書き込み、更新が可能に。

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 Sybase PowerBuilder. This article shows how to connect to ServiceNow data and execute queries from the Database Painter and controls such as the DataWindow.


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. If you have not already done so, create an ODBC DSN for ServiceNow. The DSN contains the connection properties required to connect to ServiceNow data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • OAuthClientId
    • OAuthClientSecret
    • Username
    • Password
    • Instance

    ServiceNow はOAuth 2.0 認証標準を利用しています。OAuth を使って認証するには、ServiceNow にOAuth アプリを登録してOAuthClientId を取得しなければなりません。OAuth 値の他に、Instance、User、およびPassword の指定が必要です。

    OAuth 認証を介した接続について詳しくは、ヘルプドキュメントの「OAuth 認証の使用」を参照してください。

    See the help documentation for a guide to creating a ServiceNow DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the ServiceNow DSN in the Data Source menu.
  5. 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();
