Connect to Snowflake Data in NetBeans

The CData JDBC Driver for Snowflake integrates connectivity to live Snowflake 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 Snowflake data in NetBeans. You will create a connection and edit and save Snowflake data in the Table Editor.

Create a JDBC Data Source for Snowflake 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.snowflake.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.snowflake.SnowflakeDriver 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 Snowflake.
   • 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.

     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.

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

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.snowflake.jar

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

     A typical JDBC URL is the following:

     jdbc:snowflake:User=Admin;Password=test123;Server=localhost;Database=Northwind;Warehouse=TestWarehouse;Account=Tester1;

Query Snowflake Data

To connect to Snowflake 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.
