DataBind Controls to MYOB AccountRight データ in C++Builder
DataBind to MYOB AccountRight のデータ in C++Builder with standard components and controls.
最終更新日：2023-06-12The CData ODBC Driver for MYOB AccountRight makes it easy to integrate connectivity to live MYOB AccountRight のデータ 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 MYOB AccountRight のデータ, 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 MYOB AccountRight 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.
MYOB への接続
MYOB 会社ファイルに接続するには、CompanyFileId をデータを取得したい会社ファイルのID に設定します。指定しない場合は、最初に返された会社ファイルのID（アルファベット順にソート）が使用されます。
この接続プロパティは、CompanyFiles ビューを除くすべてのテーブルおよびビューにアクセスするために必要です。CompanyFiles ビューは、アカウントに紐づく会社ファイル（およびその関連ID）を表示するために使用できます。会社ファイルのID がわからない場合は、このビューを使用してください。
次のプロパティを追加設定します。
| オンプレミスインスタンス | Instance：OnPremise に設定。 |
| AuthScheme：Basic に設定。 | |
| User：会社のファイルに紐づいているユーザー名。会社ファイルを作成すると、Administrator というユーザーアカウントが自動的に作成されます。デフォルトでは、Administrator ユーザーアカウントにはパスワードが割り当てられません。 | |
| InitiateOAuth：OFF。 | |
| Url：MYOB インスタンスのURL。 | |
| クラウドインスタンス | Instance：Cloud に設定。 |
| AuthScheme：OAuth に設定。 | |
| InitiateOAuth：GETANDREFRESH。 | |
| User：会社のファイルに紐づいているユーザー名。 | |
| Password：（パスワードが設定されている場合）会社ファイルの認可されたユーザーのパスワードに設定。 |
OAuth で認証する場合は、さらにヘルプドキュメント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 MYOB AccountRight.
- 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 MYOB AccountRight.
Create VCL Applications with Connectivity to MYOB AccountRight データ
Follow the procedure below to start querying MYOB AccountRight のデータ 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 MYOB AccountRight.
- 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, Name FROM Accounts WHERE Type = 'Bank'- 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.
Execute Commands to MYOB AccountRight with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to MYOB AccountRight のデータ. This section provides myobaccountrightspecific examples of executing queries with the TFQuery component.
Connect to MYOB AccountRight 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 MYOB AccountRight ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to MYOB AccountRight のデータ, 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 type = :Type";
FDQuery1->ParamByName("type")->AsString = "Bank";
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 type = :Type";
FDQuery1.ParamByName("type")->AsString = "Bank";
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;
