## SQL Average (AVG) Function
|
|
|
|
"Average" is an Aggregate (Group By) Function. It's used to calculate the average of a numeric column from the set of rows returned by a SQL statement.
|
|
|
|
Here is the syntax for using the function:
|
|
|
|
```sql
|
|
select groupingField, avg(num_field)
|
|
from table1
|
|
group by groupingField
|
|
```
|
|
|
|
Here's an example using the student table:
|
|
|
|
```sql
|
|
select studentID, FullName, avg(sat_score)
|
|
from student
|
|
group by studentID, FullName;
|
|
```
|
