Connect to CockroachDB Data in DBeaver

The CData ODBC Driver for CockroachDB enables access to live data from CockroachDB under the ODBC standard, allowing you work with CockroachDB data in a wide variety of BI, reporting, and ETL tools and directly, using familiar SQL queries. This article shows how to manage CockroachDB data with visual tools in DBeaver like the query browser.

The CData ODBC drivers offer unmatched performance for interacting with live CockroachDB data in DBeaver due to optimized data processing built into the driver. When you issue complex SQL queries from DBeaver to CockroachDB, the driver pushes supported SQL operations, like filters and aggregations, directly to CockroachDB and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can manage and analyze CockroachDB data.

Connect to CockroachDB

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can configure the DSN using the Microsoft ODBC Data Source Administrator. This is also the last step of the driver installation. See the "Getting Started" chapter in the Help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Finally, set the "Map To WVarchar connection property to False in the DSN Configuration window for the driver. This configuration will allow string types to be mapped to SQL_VARCHAR and prevent SQL_WVARCHAR types from being displayed as NULL.

Connecting to the CockroachDB ODBC Data Source in DBeaver

1. Open the DBeaver application and in the Database menu, select the New Database Connection option.
2. In the 'Connect to a database' window, select ODBC and click Next.
3. In the Database/Schema field, enter the DSN name (CData CockroachDB Source by default). It will be automatically added to the JDBC URL as well.
4. Click the Test Connection button. You should receive a 'Connected' message after DBeaver has detected the DSN, along with details about the driver if the connection is successful.

Query CockroachDB Data

You can now query information from the tables exposed by the data source connection. You can expand the database structure in order to view all the tables. You can retrieve the table's data by right-clicking on a table name and selecting View data. The data will then be available in the Data tab.
