How to view Oracle データ in RAD Studio Data Explorer using the CData ODBC Driver for Oracle.
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 Oracle, you gain access to live Oracle データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Oracle データ. This article will walk through connecting to Oracle using the Data Explorer.
Configure a Connection to Oracle
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.
Oracle への接続には、PATH variable をアップデートして、ネイティブDLL が含まれるフォルダロケーションが含まれていることを確認します。ネイティブDLL は、インストールディレクトリのlib フォルダにあります。完了したら次のプロパティを設定します:
- Port: Oracle データベースをホストしているサーバーに接続するポート。
- User: Oracle データベースに接続するユーザーのID。
- Password: Oracle データベースに接続するユーザーのパスワード。
- Service Name: Oracle データベースのサービス名。
Connecting to Oracle データ Using Data Explorer
You can create a simple application for displaying Oracle データ by utilizing the CData FireDAC Components for Oracle and a new VCL Forms Application:
- Open the Data Explorer in RAD Studio and expand FireDAC.
- 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 Oracle.
- Back in the Data Explorer, expand the tables for the connection.
Create a new VCL Forms application and drag a table (for example: Customers) onto the form.
- Select the CustomersTable object on the form and set the Active property to true.
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 Customers data.
