English version:
To search for latitude and longitude (coordinates) for create a google map at qlikview, I'm using a 'For' that goes line by line from my table to use the "GeocodeResponse'.
But my table is giant, because I use a sql database. You can see how i did it right below.
Question: Is there a better way to use this method without go record by record from the table?
---------------------------------
Portuguese version:
Para criar minha tabela de clientes com latitude e longitude usando busca do google, Utilizo de um For para percorrer registro por registro da minha tabela e buscar as coordenadas usando GeocodeResponse, conforme o exemplo abaixo. Como uso banco de dados sql server, a minha base de dados é enorme, não posso ficar gerando linha por linha.
Pergunta: Alguém pode me indicar uma maneira mais prática e rápida de buscar estas informações, sem ser por esta forma?
---------------------------------
Exemplo:
// Frete is my table from sql server database.
Let noRows = NoOfRows('Frete')-1;
For i=0 To $(noRows)
Let a = peek('CliDev',$(i),'Frete');
Let b = peek('Devedor',$(i),'Frete');
Let c = peek('CidadeDev',$(i),'Frete');
Let d = peek('UFDev',$(i),'Frete');
GeocodeResponse:
LOAD
'$(a)' as CliDeveM,
'$(b)' as DevedorMa,
'$(c)' as CidDevM,
'$(d)' as UFDevM,
([result/geometry/location/lat]) as Latitude,
([result/geometry/location/lng]) as Longitude
FROM [http://maps.googleapis.com/maps/api/geocode/xml?address=CidDevM&sensor=false] (XmlSimple, Table is [GeocodeResponse]);
next i;
I would recommend that you store the already geocoded address into a qvd and only geocode new addresses on reload.
Sadly Google don't allow you to geocode in batch.
Thank you Alexander,
That was a good idea. I got all the coordinates from google maps and I saved in one qvd, just like you said.
For all my others reports, I'll use that one.
