One of your answers are incorrect it said 1090 wasn't returned. However 1090 was returned. #standardSQL # pull ID fields from both tables SELECT DISTINCT website.productSKU AS website_SKU, inventory.SKU AS inventory_SKU FROM `data-to-insights.ecommerce.all_sessions_raw` AS website JOIN `data-to-insights.ecommerce.products` AS inventory ON website.productSKU = inventory.SKU # IDs are present in both tables, how can we dig deeper?
