WHERE employees.job_id = jobs.job_id;
Problem (7)
-Create a list of every employee’s job, the salary ranges within the job, and the

"Employee Name", jobs.job_title "Jobs", MIN_SALARY ||'-'|| MAX_SALARY "Salary
Range", employees.salary "Employee's Salary"
FROM Employees, Jobs
WHERE employees.job_id = jobs.job_id;
Problem (8)
