Build a Simple VCL Application for Airtable データ
How to build a simple VCL Application to view Airtable データ in RAD Studio using the CData ODBC Driver for Airtable.
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 Airtable, you gain access to live Airtable データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve Airtable データ. This article will walk through connecting to Airtable and creating a simple VCL application with the Form Designer.
Create a Connection to Airtable 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.
Airtable への接続には、APIKey、BaseId、TableNames のプロパティが必須です。ViewNames は任意項目でテーブルのビューを指定することができます。
- APIKey : アカウントのAPI Key。取得には、アカウントにログインして、API セクションで「Generate API Key」をクリックします。
- BaseId : ベースのId。取得には、APIKey と同じ場所で、「Airtable API」をクリックするか、https://airtable.com/api に進み、ベースを選択します。"The ID of this base is appxxN2ftedc0nEG7." というメッセージがIntroduction セッションで表示されます。
- TableNames : 選択されたベースのテーブル名のカンマ区切りのリスト。UI で見られるテーブル名と同じです。
- ViewNames : table.view 形式のビューのカンマ区切りのリスト。UI でみられるビュー名と同じです。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Airtable 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 Airtable.
Create VCL Applications with Connectivity to Airtable データ
Follow the procedure below to start executing queries to Airtable 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 Airtable 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, Column1 FROM SampleTable_1 WHERE Column1 = 'Value1'- 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.
