Answer 1

不完全确定你想要什么，但听起来像这样。根据需要在select query中添加其他列。

http://sqlfiddle.com/#!9/cfb31c/5/0

select e.last_name,e.salary,e.department_id from
employee e inner join department d
on e.department_id=d.department_id
where d.department_name in ('IT','MARKETING')
and e.salary > (select min(e1.salary) from employee e1
                inner join department d1
                where e1.department_id=d1.department_id
                and d1.department_name = 'ACCOUNTING')
order by e.last_name

<强>更新

同一声明，重新格式化。
还删除了inner关键字和固定on子句，因此SQL是供应商中立的，即适用于MySQL，MS SQL，Oracle，PostgreSQL，......

select e.last_name, e.salary, e.department_id
  from employee e
  join department d on d.department_id = e.department_id
 where d.department_name in ('IT','MARKETING')
   and e.salary > ( select min(e1.salary)
                      from employee e1
                      join department d1 on d1.department_id = e1.department_id
                     where d1.department_name = 'ACCOUNTING' )
 order by e.last_name
