The CData ODBC Driver for Dynamics 365 Business Central makes it easy to integrate connectivity to live Dynamics 365 Business Central データ with standard data access components in C++Builder. This article shows how to create a simple visual component library (VCL) application in C++Builder that connects to Dynamics 365 Business Central データ, executes queries, and displays the results in a grid. An additional section shows how to use FireDAC components to execute commands from code.

Create a Connection to Dynamics 365 Business Central 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.

Dynamics 365 Business Central 接続プロパティの取得・設定方法

Dynamics 365 Business Central への認証には、User およびAccessKey プロパティが必要です。

データに接続するには、OrganizationUrl を指定します。OrganizationUrl は、 http://businesscentral.dynamics.com/abc123/ などのBusiness Central アカウントへのエンドポインであるか、Web サービスのルートを参照する必要があります。OrganizationUrl を指定する方法 および利用可能なエンドポイントについての詳細は、Business Central エンドポイント を参照してください。組織内に複数の会社がある場合は、どの会社に接続するかを特定するためにCompany を指定する必要があります。 会社が1つだけの場合は、Company を指定する必要はありません。

Dynamics 365 Business Central に認証するには、User およびAccessKey 接続プロパティを指定します。Microsoft では、これらをテストおよび開発目的で推奨します。ただし、運用環境での使用は推奨していません。User およびAccessKey の値を取得するには、Dynamics 365 Business Central の「ユーザー」ページに移動して「編集」をクリックします。User Name および Web Service Access Key の値は、User およびPassword 接続文字列プロパティとして入力する値です。User Name はE メールアドレス ではありません。短縮されたユーザー名です。

Microsoft では、OAuth 認証を使用する本番ユースケースを推奨します。詳細については、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。

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Dynamics 365 Business Central.

  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 Dynamics 365 Business Central.

Create VCL Applications with Connectivity to Dynamics 365 Business Central データ

Follow the procedure below to start querying Dynamics 365 Business Central 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 Dynamics 365 Business Central.
    • 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
    • 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.

Execute Commands to Dynamics 365 Business Central with FireDAC Components

You can use the TFDConnection and TFQuery components to execute queries to Dynamics 365 Business Central データ. This section provides Dynamics 365 Business Central-specific examples of executing queries with the TFQuery component.

Connect to Dynamics 365 Business Central データ

To connect to the data source, set the Connected property of the TFDConnection component to true. You can set the same properties from code:

FDConnection1->ConnectionDefName = "CData Dynamics 365 Business Central ODBC Source"; FDConnection1->Connected = true;

To connect the TFDQuery component to Dynamics 365 Business Central データ, set the Connection property of the component. When a TFDQuery component is added at design time, its Connection property is automatically set to point to a TFDConnection on the form, as in the application above.

Create Parameterized Queries

To create a parameterized query, use the following syntax below:

FDQuery1->SQL->Text = "select * from Accounts where name = :Name"; FDQuery1->ParamByName("name")->AsString = "MyAccount"; query->Open();

The example above binds a string-type input parameter by name and then opens the dataset that results.

Prepare the Statement

Preparing statements is costly in system resources and time. The connection must be active and open while a statement is prepared. By default, FireDAC prepares the query to avoid recompiling the same query over and over. To disable statement preparation, set ResourceOptions.DirectExecute to True; for example, when you need to execute a query only once.

Execute a Query

To execute a query that returns a result set, such as a select query, use the Open method. The Open method executes the query, returns the result set, and opens it. The Open method will return an error if the query does not produce a result set.

FDQuery1->SQL->Text := "select * from Accounts where name = :Name"; FDQuery1.ParamByName("name")->AsString = "MyAccount"; FDQuery1->Open();

To execute a query that does not return a result set, use the ExecSQL method. The ExecSQL method will return an error if the query returns a result set. To retrieve the count of affected rows use the TFD.RowsAffected property.

FDQ.SQL.Text := "delete from Accounts where Id = :Id"; FDQuery1->Params->Items[0]->AsString = "x12345"; FDQuery1->ExecSQL(); AnsiString i = FDQuery1->RowsAffected;
