Hi can somebody help me with some queries for my problem database.
I want to report:
1. Which device/software that (practically) never shows up some problems.
2. A top 10 of the most occuring problems
3. The need of more time that a employee needs to solve a problem over the
average solving time.
I am just beginning to study sql so my knowledge is very low. :(
Can some body help me with these queries?
Greets,
Menno Pieper
