You want to create a histogram for the salaries of all employees whose salary amount ranges between $70000 and $200000. The width of each partition, or bucket, within the specified range is to be $32500.
The employee salary table contains eight employees:

You perform the following SELECT statement.
SELECT salary, WIDTH_BUCKET(salary,70000,200000,4),COUNT(salary)
FROM emp_salary
