Build a Simple VCL Application for SAP Fieldglass データ
How to build a simple VCL Application to view SAP Fieldglass データ in RAD Studio using the CData ODBC Driver for SAP Fieldglass.
最終更新日：2023-06-12Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for SAP Fieldglass, you gain access to live SAP Fieldglass データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve SAP Fieldglass データ. This article will walk through connecting to SAP Fieldglass and creating a simple VCL application with the Form Designer.
Create a Connection to SAP Fieldglass データ
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.

運用環境への認証を行うには、以下のように指定します。
- APIKey：SAP Fieldglass API キー。これはオプションですが、API キーが必要であることを示すSAP Fieldglass からのエラーが発生した場合は、SAP Fieldglass 管理者に依頼するか、SAP Fieldglass Integration Tools にログインしてCreate API Application をクリックします。
- OAuthClientId：SAP Fieldglass 担当者から取得したOAuth Client ID。
- OAuthClientSecret：SAP Fieldglass 担当者から取得したOAuth Client Secret。
- EnvironmentURL：SAP Fieldglass 担当者から取得したSAP Fieldglass Environment URL。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to SAP Fieldglass データ.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- 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 SAP Fieldglass.
Create VCL Applications with Connectivity to SAP Fieldglass データ
Follow the procedure below to start executing queries to SAP Fieldglass データ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to SAP Fieldglass データ.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
Drop a TFDQuery component onto the form and set the properties below:
- Connection: Set this property to the TFDConnection component, if this component is not already specified.
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'- Active: Set this property to true.
Drop a TDataSource component onto the form and set the following property:
- DataSet: In the menu for this property, select the name of the TFDQuery component.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.
You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
