This is a more complex example from the campaign contributions table. This example has a GROUP BY clause with a HAVING clause using an AND to restrict the returned records to candidates from 2016 with contributions between $3 Million and $18 Million in total.
```sql
select Candidate, Office_Sought, Election_Year, FORMAT(sum(Total_$),2) from combined_party_data
where Office_Sought = 'PRESIDENT / VICE PRESIDENT'
group by Candidate, Office_Sought, Election_Year
having Election_Year = 2016 and sum(Total_$) between 3000000 and 18000000
order by sum(Total_$) desc;
