Week 53 – Intermediate

One of the quieter releases into public preview is that we can now infer schemas for CSVs. To test this follow the following instructions:

    skip_header = 1;
  3. PUT the following csv file into that internal stage. Download Here

    thanks for the challenge — had to `put` the file outside my solution, but good to explore these new functionalities (also useful to combina with other metadata functions!)
