Question

I have a log table with following schema:

OperatorId - JobId - Status ( Good/Bad/Ugly )
Alex         6       Good
Alex         7       Good
James        6       Bad

Description: Whenever an operator works on a job, an entry is made along with Status. That’s it.

Now I need a report like:

OperatorId - Good Count - Bad Count - Ugly Count
Alex         2            0           0
James        0            1           0

Answer 1

select operatorid,
sum(if(status="good",1,0)) as good,
sum(if(status="bad",1,0)) as bad,
sum(if(status="ugly",1,0)) as ugly
from table
group by operatorid
