Connect to CockroachDB Data in NetBeans

The CData JDBC Driver for CockroachDB integrates connectivity to live CockroachDB data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to CockroachDB data in NetBeans. You will create a connection and edit and save CockroachDB data in the Table Editor.

Create a JDBC Data Source for CockroachDB in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

• Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.cockroachdb.jar file. The driver JAR is located in the lib subfolder of the installation directory.
• Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.cockroachdb.CockroachDBDriver from the menu.
• Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

1. In the Service window, right-click the Database node and click New Connection.

2. In the New Connection Wizard, enter the following connection properties:

   • Driver Name: In the menu, select the CData JDBC Driver for CockroachDB.
   • User Name: Enter the username. This can also be defined in the JDBC URL.
   • Password: Enter the password. This can also be defined in the JDBC URL.

   • JDBC URL: Specify the JDBC URL.

     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.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the CockroachDB JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.cockroachdb.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     A typical JDBC URL is the following:

     jdbc:cockroachdb:User=root;Password=root;Database=system;Server=localhost;Port=26257

Query CockroachDB Data

To connect to CockroachDB data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data. You can also insert, update, or delete records in the Data Views window.
