Olá pessoal,
Boa noite!
Nesse post vou dar uma dica bem rapidinha de como consumir a API do Google Maps usando OLE Automation no SQL Server para recuperar mais informações de uma cidade apenas pelo seu nome.
Não sabe como ativar OLE Automation na sua instância? Veja mais no post Habilitando OLE Automation via T-SQL no SQL Server.

And that's it, folks!

Aí sim!! ??
Este script não funciona com geolocalização reversa? Ou seja, buscar por coordenadas (https://maps.googleapis.com/maps/api/geocode/xml?language=pt-BR&latlng=Lat,Lgn).
Boa ideia!!
