To filter by city inside a VARIANT column when querying weather data, which syntax is used?

Explanation:
Accessing data inside a VARIANT uses the path notation: column:field. When the VARIANT column contains an object with a city field, you pull that value with V:city and convert it to the expected type before comparing. So filtering with V:city::STRING = 'HARTFORD' reads the city value from the VARIANT, casts it to STRING, and checks equality to 'HARTFORD'. The other forms try to reference a path in the wrong order or structure (city:V, TEMPVAL:city, CITY:city), which Snowflake won’t interpret as the city field inside the VARIANT. Casting to STRING is a safe, explicit way to ensure a proper comparison.
