I have a table with columns
Type, Login, and
Timestamp. It has been collecting information about the type of browsers users log into the system with for years. Obviously many of the users have since upgraded their browsers. I do not want to consider data for old browsers when users have upgraded. Here is the query I currently have to get a count of how many people use which browser:
select Type, count(Type) as Count from (select distinct Login, Type from BROWSER) as q group by Type
This appears to work fine, but I have a lot of old browsers that I know are no longer being used:
How would I only select the most recent browser used by each user based on timestamp (or Browser_ID could work also since they are written sequentially). I also intend to ignore data by users who have not logged in during the past year, but that is simple to add later (I only mention it so that no one brings up why I would want browser data that is old for inactive users - I do plan on addressing that as well but I know how to do that already).
If anyone is up for a challenge, there are some users who log in from a couple different computers - or perhaps from their phone and from their desk. It would be great if I could determine that they frequently log in from two different places and also collect that data, but this might be too complicated. If anyone figured out how to add this complicated step, I'll gladly award a 50 point bounty to the answer.
