oracl数据库sql语句怎么查询工资最低的两名员工编号，姓名，工资等信息。

查询每个部门工资最低的两个员工编号，姓名，工资，等信息。关键是工资最低的两名员工

select top(2) from (select * from emp order by salary desc)

 select * from (
select a.*, row_number()over(partition by 部门 order by 工资)  rn from 表
) where rn<=2

select * from emp order by salary asc, 他们写的好像都是sqlserver的， 用这条语句查询最前面两天条就好了。

select * from emp order by salary asc limit 2好像就可以

 SELECT
    *
FROM
    (
        SELECT
            bumen,
            price,
            ROW_NUMBER () OVER (
                PARTITION BY bumen
                ORDER BY
                    bumen,
                    price DESC
            ) rn
        FROM
            table1
        WHERE
            bumen IN (
                SELECT
                    bumen
                FROM
                    table1
                GROUP BY
                    bumen
            )
    )
WHERE
    rn < 3

我改了一下上面的代码，加了一个表的别称：

SELECT *
FROM ( SELECT a.* ,
ROW_NUMBER() OVER ( PARTITION BY 部门 ORDER BY 工资 ASC ) rn
FROM 表 a
) a
WHERE rn <= 2
