I have a table with all zip codes for Germany with their geo infortmation. After uploading it in cartoDB, it works to Show all of the different zip codes.
Now I want to Group the zip codes by their three leading Digits. That I want to Display in a Google map using that API.
Online I already found a few good sources, but not how to Group the zip codes.
Any ideas?

Christian
