Build a Simple VCL Application for SAP ByDesign データ
How to build a simple VCL Application to view SAP ByDesign データ in RAD Studio using the CData ODBC Driver for SAP ByDesign.
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 ByDesign, you gain access to live SAP ByDesign データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve SAP ByDesign データ. This article will walk through connecting to SAP ByDesign and creating a simple VCL application with the Form Designer.
Create a Connection to SAP ByDesign 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.
SAP ByDesign に接続するには、次の接続プロパティを設定します。
- Url: SAP ByDesign サイトのURL に設定。例：https://test.sapbydesign.com
- User: アカウントのユーザー名に設定。
- Password: アカウントのパスワードに設定。
- CustomService or AnalyticsService: いずれか一方のみを指定する必要があります。データを取得するカスタムサービスがある場合はCustomService を指定します。アナリティクスサービスのレポートを取得する場合はAnalyticsService を指定します。 どちらも指定されていない場合は、'cc_home_analytics.svc' がAnalyticsService プロパティのデフォルトとして使用されます。指定するサービスがわからない場合は、Services ビューをクエリして利用可能なサービスを一覧表示できます。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to SAP ByDesign 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 ByDesign.
Create VCL Applications with Connectivity to SAP ByDesign データ
Follow the procedure below to start executing queries to SAP ByDesign 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 ByDesign 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, ProductCategoryID FROM [Inventory Balance] WHERE ProductCategoryID = '1234567'- 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.
