从员工表中选择前10名薪水

Question

我写了这个SQL查询:

select first_name, salary 
from employees 
where salary in( select distinct top(10) salary from employees order by salary  disc );

当我运行它时,我收到此错误:

SQL错误:ORA-00907:缺少右括号00907. 00000 - "缺少右括号"

什么可能导致错误？

Answer 1

Top-N查询通常在Oracle中以这种方式执行:

select * from (
select first_name, salary 
from employees order by salary desc
) where rownum <= 10

这个可以获得十大薪水.
