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 Cassandra, you gain access to live Cassandra データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Cassandra データ. This article will walk through connecting to Cassandra 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.
Cassandra への接続には、Server、Port、Database を接続プロパティとして設定します。追加で、内部認証を使う場合には、User、Password を接続プロパティに設定します。
You can create a simple application for displaying Cassandra データ by utilizing the CData FireDAC Components for Cassandra and a new VCL Forms Application:
Create a new VCL Forms application and drag a table (for example: Customer) 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 Customer data.
