How to Connect to Snowflake in Sigma

By Joe McFarren

When working with a new data visualization or business intelligence tool, one of the most important first steps is connecting to a data source. Whether that is a flat CSV or a live connection to a cloud data warehouse, this can be a confusing task for some platforms.

Using Sigma, you can connect to your Snowflake Data Cloud data source in just a few very quick steps. After this, be sure to check out our other posts about Sigma to continue your journey using Sigma Computing.

How to Connect to Snowflake

When using Sigma Computing and connecting to a new data source, we feel that Snowflake is the easiest data warehouse to set up. You only need a few simple steps and you will be able to connect to your data sets in no time.

First, from your admin console, select ‘Connections’ on the left-hand side. This will allow you to view what connections you can make in Sigma. You’ll see a few options, but we are going to select Snowflake for this exercise. You will see boxes to input the following information:

  • Name – this is your connection name. You can name it whatever you want, but we recommend naming it something similar to the table you will connect to. Here I’ve titled it ‘My phData Snowflake Connection’.
  • Type – this dictates the type of data source. In this case, we are selecting Snowflake.
  • Connection Credentials – this is all of the information you need to provide to connect to your organization’s Snowflake instance. You will need your server, warehouse, user, password, and role (optional).
  • Connection timeout – this is optional and will dictate how long a query will run before it will timeout. This is up to you, but typically users will use 120 seconds.
  • Enable write access – this is also optional, but you can select this if you intend to materialize your data set.

Following the input of this information, click the create button to create your Snowflake connection. Really, that’s it. You’re now connected to your organization’s Snowflake instance.

Now, to access the tables in your Snowflake connection, go to your Sigma homepage and select Create New at the top left-hand corner of the screen and select Workbook:

At the next screen, select Table. The following screen, Tables, and Datasets. From here, you will see a section titled ‘Select a Source’:

In this example, I have connected to the Sigma Sample Database. In your case, you will see the connection name that you input in the previous steps. Navigate through the dropdowns to select your schema and table, and click the table you want to connect to. 

You will see the data set show up and from here, you can select the columns you want to bring it. This is great if there are unnecessary index columns or other information you don’t need:

Select your columns, select Done in the top right corner, and Sigma will automatically create a new workbook for you with only the information that you selected. This is a great way to narrow down the data you bring in to avoid the arduous task of hiding all of the columns you don’t need.

Pro Tip – You can connect to Snowflake via Sigma or via Snowflake Partner Connect. With the latter, you must be ACCTADMIN to connect via Partner Connect, so reach out to your Snowflake admin with any questions you may have regarding connecting to Sigma.
