This is an advanced version of the basic Database Query Exercise. You should probably do that one first.
The same instructions apply:
- Some tasks can be solved with one single query, other tasks may require a set of queries with human interaction in between. Please point out what to look for in the result set and anything else that should be kept in mind.
- If possible explain how the results can be validated.
With the following addition: Make sure that you use the existing indices on large tables such as gameEvents and itemlog.
