For task 5: - I can't update the new columns to the table covid_223.oxford_policy_tracker_101 added through schema, it works only with adding them through code and specifying for integer ang float columns 64 length. - ambigous reference for country_name in bigquery-public-data.covid19_google_mobility.mobility_report, it name is country_region, that could means something else than country_name. And I didn't find any references for contry_region meaning(that is stored country_name)
