Viewing CockroachDB Data in RAD Studio Data Explorer


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

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 data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update CockroachDB data. 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.

Set the following to connect to CockroachDB.

  • Server: The host name or IP address of the server.
  • Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
  • Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
  • User: The Cockroach DB user account used to authenticate.
  • Password: The password used to authenticate the user.

Connecting to CockroachDB Data Using Data Explorer

You can create a simple application for displaying CockroachDB data by utilizing the CData FireDAC Components for CockroachDB 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 CockroachDB.
  6. Back in the Data Explorer, expand the tables for the connection.

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

  8. Select the OrdersTable 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 Orders data.
