表的结构（表名为sqltest）
1、首先找出每一个部门的平均工资
SELECT AVG(salary) avg_salary ,depart_id FROM sqltest GROUP BY depart_id得到
2、将其作为暂时表（temp_table）。放到主查询中
SELECT sqltest.name,sqltest.salary,temp_table.depart_id,temp_table.avg_salary
FROM sqltest,(SELECT AVG(salary) avg_salary ,depart_id FROM sqltest GROUP BY depart_id) temp_table
WHERE sqltest.depart_id = temp_table.depart_id and sqltest.salary > temp_table.avg_salary;得到
