All you need is Google Internet to do a Data Analyst’s job (2)

I have to say that I am really impressed by the persistence of this candidate. I received several emails from him today. Of cause it has links to a couple of discussions on Internet with titles such as “How to UPDATE One Record From Two Records”.

Reading those online discussions is not a easy task. So I skipped it and sent him another very polite email.

Sorry I didn’t get back to you sooner.

I guess we didn’t really complete our conversation about the IP addresses over the phone. So it will be pointless for me to comment on your work.

I really appreciate your time!

Some interesting emails from him:

Of course, this is where meta-data logging would be important: We would need to let someone know what we did, and why… even if we did not do a commit…?

Thanks & comments welcome

Thanks – excellent advice. Data normalization is always interesting. –I used to joke that there needed to be a final rule – “de-normalize for speed.”

😉

So I assume that we have a single table with all IP addresses in therein. What SQL would you use to merge two records?
