## SQL AND operator

AND is used in a WHERE clause or a GROUP BY HAVING clause to limit the rows returned from the executed statement.  Use AND when it's required to have more than one condition met.

We'll use the student table to present examples.

Here's the student table without a WHERE clause:
```sql
select * from student;
```

Now the WHERE clause is added to display only programming students:
```sql
select * from student 
where programOfStudy = 'Programming';
```

Now the WHERE clause is updated with AND to show results for programming students that also have a SAT score greater than 800:
```sql
select * from student 
where programOfStudy = 'Programming' 
and sat_score > 800;
```

This is a more complex example from the campaign contributions table. This example has a GROUP BY clause with 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;
```
