Build a Simple VCL Application for UM SaaS Cloud データ
How to build a simple VCL Application to view UM SaaS Cloud データ in RAD Studio using the CData ODBC Driver for UM SaaS Cloud.
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 UM SaaS Cloud, you gain access to live UM SaaS Cloud データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update UM SaaS Cloud データ. This article will walk through connecting to UM SaaS Cloud and creating a simple VCL application with the Form Designer.
Create a Connection to UM SaaS Cloud 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.
UM SaaS Cloud 接続プロパティの取得・設定方法
デフォルトでは、本製品は本番環境に接続します。UMSaaSCloud sandbox アカウントを使用するには、UseSandbox をtrue に設定します。ユーザー / パスワード認証を使用している場合は、User にsandbox のユーザー名を設定してください。
UM SaaS Cloud への認証
UM SaaS Cloud は、Basic、OAuth、OAuthJWT（コンシューマーキー）など、複数の認証方式をサポートしています。ここではBasic 認証について説明します。認証情報の詳しい取得方法や他の認証方法については、ヘルプドキュメントの「はじめに」セクションを参照してください。
Basic 認証
Basic 認証は、セキュリティトークンとユーザー資格情報の使用に基づきます。Basic 認証を使用するには、AuthScheme をBasic に、User とPassword をログイン資格情報に設定し、SecurityToken を設定します。
デフォルトではSecurityToken が必要ですが、UM SaaS Cloud で信頼できるIP アドレスの範囲を設定することで、オプションにすることができます。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to UM SaaS Cloud 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 UM SaaS Cloud.
Create VCL Applications with Connectivity to UM SaaS Cloud データ
Follow the procedure below to start executing queries to UM SaaS Cloud 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 UM SaaS Cloud 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 BillingState, Name FROM Account WHERE Industry = 'Floppy Disks'- 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.
