Answer:
Select SUM(HOURS), SUM(CHARGES) from employees
Explanation:
The table structure is not given. So, I will assume that the table name is "employees", the columns to retrieve are "hours" and "charges"
Having said that, the function to retrieve the total of column is the sum() function.
So, the query is as follows:
Select ----> This means that the query is to retrieve from the table
SUM(HOURS), SUM(CHARGES) --- This represent the records to retrieve
from employees ---- This represents the table to retrieve from.
Creating a model provides a practical solution for some scientific research by showing systems that are very large,small,or complex.Models are simplified representations of real objects or systems.Models can make things easier to study by zooming in on a single piece of a large system or magnifying something that is too tiny to see with the naked eye.
