When working with data it's likely that you will have the need to query across a couple of different sources. In this example we will show you how to do this with a Google Sheet and a CSV file.
SELECT d.Symbol, c.Security, c.Executive, d.Price FROM (SELECT a.Symbol as Symbol, a.Security as Security, b.Executive as Executive
FROM "<https://raw.githubusercontent.com/dylanroy/sandp500-dataset/main/data.csv>" a
JOIN "<https://raw.githubusercontent.com/dylanroy/ceo-dataset/main/data.csv>" b ON a.Security = b.Company) c
JOIN "<https://docs.google.com/spreadsheets/d/1u0RkdS8KBwvCvSSIiS-xCN-P1RAfhgNRVewysHGIOrg>" d ON c.Symbol = d.Symbol
