詳細はこちら →Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for GraphQL, you gain access to live GraphQL データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update GraphQL データ. This article will walk through connecting to GraphQL using the Data Explorer.
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.
GraphQL サービスのURL を指定する必要があります。 ドライバーは2種類の認証をサポートします。
You can create a simple application for displaying GraphQL データ by utilizing the CData FireDAC Components for GraphQL and a new VCL Forms Application:
Create a new VCL Forms application and drag a table (for example: Users) onto the form.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).
Arrange the TStringGrid on the form and run the application to see the Users data.
