Build a Simple VCL Application for Microsoft Dataverse データ

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Microsoft Dataverse, you gain access to live Microsoft Dataverse データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Microsoft Dataverse データ. This article will walk through connecting to Microsoft Dataverse and creating a simple VCL application with the Form Designer.

Create a Connection to Microsoft Dataverse 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.

ユーザー資格情報の接続プロパティを設定せずに接続できます。接続に最小限必要な接続プロパティは、以下のとおりです。

• InitiateOAuth: GETANDREFRESH に設定します。
• OrganizationUrl: 接続先の組織のURL、例えばhttps://organization.crm.dynamics.com などに設定。
• Tenant (optional): デフォルトと異なるテナントに認証したい場合は、これを設定します。これは、デフォルトのテナントに所属していない組織と連携するために必要です。

接続すると、CData 製品はデフォルトブラウザでOAuth エンドポイントを開きます。ログインして、CData 製品にアクセス許可を与えます。CData 製品がOAuth プロセスを完了します。

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Microsoft Dataverse データ.

1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Microsoft Dataverse.

Create VCL Applications with Connectivity to Microsoft Dataverse データ

Follow the procedure below to start executing queries to Microsoft Dataverse データ from a simple VCL application that displays the results of a query in a grid.

1. Drop a TFDConnection component onto the form and set the following properties:

   • ConnectionDefName: Select the FireDAC connection to Microsoft Dataverse データ.
   • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

2. 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 AccountId, Name FROM Accounts WHERE Name = 'MyAccount'
   • Active: Set this property to true.

3. 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.

4. Drop a TDBGrid control onto the form and set the following property:

   • DataSource: Select the name of the TDataSource.
5. 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.
