Viewing CockroachDB データ in RAD Studio Data Explorer

How to view CockroachDB データ in RAD Studio Data Explorer using the CData ODBC Driver for CockroachDB.

最終更新日：2023-06-12

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

Configure a Connection to CockroachDB

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.

CockroachDB 接続プロパティの取得・設定方法

CockroachDB に接続するには以下を設定します。

Server：サーバーのホスト名またはIP アドレス。

Database：Cockroach データベースの名前。デフォルトでは、CData 製品はユーザーのデフォルトデータベースに接続します。
User：認証に使用されるCockroach DB ユーザーアカウント。
Password：ユーザーの認証で使用されるパスワード。

Connecting to CockroachDB データ Using Data Explorer

You can create a simple application for displaying CockroachDB データ by utilizing the CData FireDAC Components for CockroachDB 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 CockroachDB.
Back in the Data Explorer, expand the tables for the connection.
Create a new VCL Forms application and drag a table (for example: Orders) onto the form.
Select the OrdersTable 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 Orders data.
