Question

我正在尝试编写此PL SQL查询，以便在输入dpt ID后从表中获得第二高的薪水。我把它放在一起，但是在输入dpt ID之后查询没有运行。

CREATE TABLE OUTPUT_LOG
  (my_column VARCHAR(250)); 
DECLARE
    v_dpt_id
BEGIN
    select dpt_id
        into v_dpt_id
    from employees
    where dpt_id = inticap('&prompt_user');
    select salary from
     (select rownum n,a.* from
        ( select distinct salary from employees order by salary desc) a)
where n = 2;
    insert into output_log (my_column)
    VALUES (||first_name||' '||last_name||' '||salary||);
end;
SELECT my_column
  FROM OUTPUT_LOG;

试试这个

您只需将查询更改为

即可

select * from employees where salary in 
(
   select salary from
     (select rownum n,a.* from
        ( select distinct salary from employees where dpt_id = initcap('&prompt_user') order by salary desc) a
        )
     where n = 2
)

此查询为所有员工提供最高薪水的员工。

我希望这可能会有所帮助。
