Build a Simple VCL Application for Amazon Marketplace データ
How to build a simple VCL Application to view Amazon Marketplace データ in RAD Studio using the CData ODBC Driver for Amazon Marketplace.
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 Amazon Marketplace, you gain access to live Amazon Marketplace データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Amazon Marketplace データ. This article will walk through connecting to Amazon Marketplace and creating a simple VCL application with the Form Designer.
Create a Connection to Amazon Marketplace 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.
Amazon Marketplace Appstore 認証を使って接続が可能です。
- Amazon Marketplace Appstore で、CData Amazon Marketplace Drivers のページを開きます。
- 「今すぐ承認」をクリックしで、「次へ」と進みます。出品者ID などの必要情報を記入してCData Drivers にAmazon Marketplace データへのアクセス権を付与します。
- 手続きが完了すると、「MWS 認証トークン」が取得できます。
- CData Drivers の接続設定画面で「Marketplace」（任意のマーケットプレイスの国）、「Sellerid」（出品者ID）、「Mwsauthtoken」（先に取得したMWS 認証トークン）を入力して接続を行います。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Amazon Marketplace 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 Amazon Marketplace.
Create VCL Applications with Connectivity to Amazon Marketplace データ
Follow the procedure below to start executing queries to Amazon Marketplace 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 Amazon Marketplace 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 AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True- 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.
