Connect to Snowflake Data in DBeaver

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

The CData ODBC drivers offer unmatched performance for interacting with live Snowflake data in DBeaver due to optimized data processing built into the driver. When you issue complex SQL queries from DBeaver to Snowflake, the driver pushes supported SQL operations, like filters and aggregations, directly to Snowflake 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 Snowflake data.

Getting Started

---

Connect to Snowflake

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.

To connect to Snowflake:

1. Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
2. Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
3. Set Warehouse to the Snowflake warehouse.
4. (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
5. (Optional) Set Database and Schema to restrict the tables and views exposed.
6. (Optional) If MFA is enabled on your Snowflake account (via Duo Security), set MFACode to the passcode generated by your Duo authenticator app.

See the Getting Started guide in the CData driver documentation for more information.

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 Snowflake ODBC Data Source in DBeaver

1. Open the DBeaver application and in the Database menu, select the New Database Connection option. 👁 Creating a new Database Connection
   
2. In the 'Connect to a database' window, select ODBC and click Next. 👁 Creating a new Database Connection
   
3. In the Database/Schema field, enter the DSN name (CData Snowflake 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. 👁 Successfully tested connection
   

Query Snowflake 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.
