Build a Simple VCL Application for Freshdesk データ
How to build a simple VCL Application to view Freshdesk データ in RAD Studio using the CData ODBC Driver for Freshdesk.
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 Freshdesk, you gain access to live Freshdesk データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Freshdesk データ. This article will walk through connecting to Freshdesk and creating a simple VCL application with the Form Designer.
Create a Connection to Freshdesk 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.
FreshDesk はbasic 認証を使用します。データへの接続には、次の接続プロパティを設定してください。
- Domain：この値を、FreshDesk アカウントに紐づけられたドメインに設定します。例えば、 https://my_domain.freshdesk.comです。
- APIKey：この値を、FreshDesk アカウントに紐づけられたAPI キーに設定します。API キーを取得するには、 サポートPortal にログインして、-> 右上端のプロファイル写真をクリック、-> プロファイル設定ページに移動します。API キーは、 右のchange password セクションの下から生成できます。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Freshdesk 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 Freshdesk.
Create VCL Applications with Connectivity to Freshdesk データ
Follow the procedure below to start executing queries to Freshdesk 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 Freshdesk 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 Id, Name FROM Tickets WHERE Status = '2'- 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.
