Viewing ServiceNow データ in RAD Studio Data Explorer

How to view ServiceNow データ in RAD Studio Data Explorer using the CData ODBC Driver for ServiceNow.

最終更新日：2023-06-12

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for ServiceNow, you gain access to live ServiceNow データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update ServiceNow データ. This article will walk through connecting to ServiceNow using the Data Explorer.

Configure a Connection to ServiceNow

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 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。

Connecting to ServiceNow データ Using Data Explorer

You can create a simple application for displaying ServiceNow データ by utilizing the CData FireDAC Components for ServiceNow and a new VCL Forms Application:

Open the Data Explorer in RAD Studio and expand FireDAC.
Right-click the ODBC Data Source node in the Data Explorer.
Click Add New Connection.
Enter a name for the connection.
In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for ServiceNow.
Back in the Data Explorer, expand the tables for the connection.
Create a new VCL Forms application and drag a table (for example: incident) onto the form.
Select the incidentTable object on the form and set the Active property to true.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).
Arrange the TStringGrid on the form and run the application to see the incident data.
