    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.

  7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query Snowflake Data

After the metadata has loaded, a new tab for the Snowflake data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:

SELECT Id, ProductName FROM Products
