Congratulations!
You just learned how to use aggregate functions to perform calculations on your data. What can we generalize so far?
COUNT()
: count the number of rowsSUM()
: the sum of the values in a columnMAX()
/MIN()
: the largest/smallest valueAVG()
: the average of the values in a columnROUND()
: round the values in the column
Aggregate functions combine multiple rows together to form a single value of more meaningful information.
