데이타베이스가 다음과 같을때 말입니다.
employee(employee-name, street, city)
works(employee-name, company-name, salary)
company(company-name, city)
manages(employee-name, manager-name)
Find the names, street addresses, and cities of residence of all employees who work for First Bank Corporation and earn more than $10,000.
