Unsure where is the problem with the Mobility data part----Its supposed to be a STRUCT yes..? table within a table? In my generated oxford_policy table - Mobility is a table in a table -- so all the AVGs are displaying as tables inside a table.... This is the code I used: UPDATE `qwiklabs-gcp-03-2cc83f0c96b3.covid_231.oxford_policy_tracker_946` t0 SET t0.mobility.avg_retail = t1.avg_retail, t0.mobility.avg_grocery = t1.avg_grocery, t0.mobility.avg_parks = t1.avg_parks, t0.mobility.avg_transit = t1.avg_transit, t0.mobility.avg_workplace = t1.avg_workplace, t0.mobility.avg_residential = t1.avg_residential FROM ( SELECT country_region, date, AVG(retail_and_recreation_percent_change_from_baseline) as avg_retail, AVG(grocery_and_pharmacy_percent_change_from_baseline) as avg_grocery, AVG(parks_percent_change_from_baseline) as avg_parks, AVG(transit_stations_percent_change_from_baseline) as avg_transit, AVG( workplaces_percent_change_from_baseline ) as avg_workplace, AVG( residential_percent_change_from_baseline) as avg_residential FROM `bigquery-public-data.covid19_google_mobility.mobility_report` GROUP BY country_region, date )AS t1 WHERE CONCAT(t0.country_name, t0.date) = CONCAT(t1.country_region, t1.date) Generates a table inside mobility column...
