Viewing Phoenix データ in RAD Studio Data Explorer

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Phoenix, you gain access to live Phoenix データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve Phoenix データ. This article will walk through connecting to Phoenix using the Data Explorer.

Configure a Connection to Phoenix

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.

Phoenix Query Server 経由でApache Phoenix に接続します。デフォルトのポートと異なる場合は、Server とPort プロパティを設定してApache Phoenix に接続します。Servre プロパティは通常、Apache Phoenix をホストしているサーバーのホスト名またはIP アドレスです。

Apache Phoenix への認証

デフォルトでは、認証は使用されません（プレーン）。サーバーに認証が設定されている場合は、AuthScheme をNEGOTIATE に設定して、 必要な場合にはUser とPassword プロパティを設定して、Kerberos で認証します。

Connecting to Phoenix データ Using Data Explorer

You can create a simple application for displaying Phoenix データ by utilizing the CData FireDAC Components for Phoenix and a new VCL Forms Application:

1. Open the Data Explorer in RAD Studio and expand FireDAC.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Phoenix.
6. Back in the Data Explorer, expand the views for the connection.

7. Create a new VCL Forms application and drag a view (for example: MyTable) onto the form.

8. Select the MyTableView object on the form and set the Active property to true.

9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

10. Arrange the TStringGrid on the form and run the application to see the MyTable data.
