How can I select the highest salary on each department with a same salary.
My query is only to get the first row in each department with the same salary. But I want to select all max same salary on each department. Please help me out of this problem.
Below is the sample table:
PSD Department
----------------------
Yumang's Salary: $500
Paus Salary: $500
QA Department
----------------------
Villanueva: $1000
Calacar: $1000
Here's the code I am trying:
SELECT MAX(inter_department_votes.number_votes)
FROM employee_salary
GROUP BY dept_id
try selecting dept_id as well:
SELECT dept_id,
MAX(inter_department_votes.number_votes)
FROM employee_salary GROUP BY dept_id
Using RANK() function:
RANK provides the same numeric value for ties (for example 1, 1, 2, 4, 5).
SELECT *
FROM (
SELECT dept_id,
PersonName,
Salary,
RANK() OVER(PARTITION dept_id ORDER BY Salary DESC) AS SortBySalary
FROM employee_salary
)
WHERE SortBySalary = 1
Also, see this answer using MAX() function.
your table isn't clear to me. i can't understand why you're creating separate tables for all departments.
assuming you make two different tables, one for employees and one for department. this will make queries simpler for future and efficient database. In that case:
+----------+------------+------+-----+
|EmployeeID|EmployeeName|Salary|DepNo|
+----------+------------+------+-----+
| |
+----------+------------+------+-----+
+-----+-------+
|DepNo|DepName|
+-----+-------+
| |
+-----+-------+
SELECT DepName, EmployeeName, salary
FROM Department d
INNER JOIN Employee e on e.DepNo = d.DepNo
INNER JOIN
(
SELECT DepNo, MAX(salary) sal
FROM Employee
GROUP BY DepNo
) ss ON e.DepNo = ss.DepNo
AND e.salary = ss.sal;
I have the following table:
and executing the following query
select distinct lastname, firstname, max(salary) as salary
from employees
where salary not in (select max(salary) from employees)
group by lastname, firstname
I get the following result:
I want to find all the names of the employees that have the second highest salary which in the given table are all those with 6000 salary, but the only answers I could find was the above query. I am looking for some time now another way to do so but I can't find anything.
I am using SQL Server. Does anyone have any suggestions?
You can use dense_rank() window function for this:
select * from (
select employees.*, dense_rank() over(order by salary desc) rnk from employees
) t
where rnk = 2
If you have Sql Server 2005 or higher you could use DENSE_RANK.
with a as(
select lastname,firstname,salary,
dense_rank()over(order by salary desc)r
from employees
)
select lastname,firstname,salary
from a where r=2;
You can try the below Sql query
DECLARE #SecondHighestSalary Int
SELECT TOP 1 #SecondHighestSalary = salary FROM (
SELECT TOP 2 salary
FROM employees
ORDER BY salary DESC) AS emp
ORDER BY salary ASC
SELECT * FROM employees where salary = #SecondHighestSalary
You can try this for getting n-th highest salary, where n = 1,2,3....(int)
SELECT TOP 1 salary FROM (
SELECT TOP n salary
FROM employees
ORDER BY salary DESC) AS emp
ORDER BY salary ASC
Hope this will help you.
It's a question I got this afternoon:
There a table contains ID, Name, and Salary of Employees, get names of the second-highest salary employees, in SQL Server
Here's my answer, I just wrote it in paper and not sure that it's perfectly valid, but it seems to work:
SELECT Name FROM Employees WHERE Salary =
( SELECT DISTINCT TOP (1) Salary FROM Employees WHERE Salary NOT IN
(SELECT DISTINCT TOP (1) Salary FROM Employees ORDER BY Salary DESCENDING)
ORDER BY Salary DESCENDING)
I think it's ugly, but it's the only solution come to my mind.
Can you suggest me a better query?
Thank you very much.
To get the names of the employees with the 2nd highest distinct salary amount you can use.
;WITH T AS
(
SELECT *,
DENSE_RANK() OVER (ORDER BY Salary Desc) AS Rnk
FROM Employees
)
SELECT Name
FROM T
WHERE Rnk=2;
If Salary is indexed the following may well be more efficient though especially if there are many employees.
SELECT Name
FROM Employees
WHERE Salary = (SELECT MIN(Salary)
FROM (SELECT DISTINCT TOP (2) Salary
FROM Employees
ORDER BY Salary DESC) T);
Test Script
CREATE TABLE Employees
(
Name VARCHAR(50),
Salary FLOAT
)
INSERT INTO Employees
SELECT TOP 1000000 s1.name,
abs(checksum(newid()))
FROM sysobjects s1,
sysobjects s2
CREATE NONCLUSTERED INDEX ix
ON Employees(Salary)
SELECT Name
FROM Employees
WHERE Salary = (SELECT MIN(Salary)
FROM (SELECT DISTINCT TOP (2) Salary
FROM Employees
ORDER BY Salary DESC) T);
WITH T
AS (SELECT *,
DENSE_RANK() OVER (ORDER BY Salary DESC) AS Rnk
FROM Employees)
SELECT Name
FROM T
WHERE Rnk = 2;
SELECT Name
FROM Employees
WHERE Salary = (SELECT DISTINCT TOP (1) Salary
FROM Employees
WHERE Salary NOT IN (SELECT DISTINCT TOP (1) Salary
FROM Employees
ORDER BY Salary DESC)
ORDER BY Salary DESC)
SELECT Name
FROM Employees
WHERE Salary = (SELECT TOP 1 Salary
FROM (SELECT TOP 2 Salary
FROM Employees
ORDER BY Salary DESC) sel
ORDER BY Salary ASC)
SELECT * from Employee
WHERE Salary IN (SELECT MAX(Salary)
FROM Employee
WHERE Salary NOT IN (SELECT MAX(Salary)
FFROM employee));
Try like this..
This might help you
SELECT
MIN(SALARY)
FROM
EMP
WHERE
SALARY in (SELECT
DISTINCT TOP 2 SALARY
FROM
EMP
ORDER BY
SALARY DESC
)
We can find any nth highest salary by putting n (where n > 0) in place of 2
Example for 5th highest salary we put n = 5
How about a CTE?
;WITH Salaries AS
(
SELECT Name, Salary,
DENSE_RANK() OVER(ORDER BY Salary DESC) AS 'SalaryRank'
FROM
dbo.Employees
)
SELECT Name, Salary
FROM Salaries
WHERE SalaryRank = 2
DENSE_RANK() will give you all the employees who have the second highest salary - no matter how many employees have the (identical) highest salary.
All of the following queries work for MySQL:
SELECT MAX(salary) FROM Employee WHERE Salary NOT IN (SELECT Max(Salary) FROM Employee);
SELECT MAX(Salary) From Employee WHERE Salary < (SELECT Max(Salary) FROM Employee);
SELECT Salary FROM Employee ORDER BY Salary DESC LIMIT 1 OFFSET 1;
SELECT Salary FROM (SELECT Salary FROM Employee ORDER BY Salary DESC LIMIT 2) AS Emp ORDER BY Salary LIMIT 1;
Another intuitive way is :-
Suppose we want to find Nth highest salary then
1) Sort Employee as per descending order of salary
2) Take first N records using rownum. So in this step Nth record here is Nth highest salary
3) Now sort this temporary result in ascending order. Thus Nth highest salary is now first record
4) Get first record from this temporary result.
It will be Nth highest salary.
select * from
(select * from
(select * from
(select * from emp order by sal desc)
where rownum<=:N )
order by sal )
where rownum=1;
In case there are repeating salaries then in innermost query distinct can be used.
select * from
(select * from
(select * from
(select distinct(sal) from emp order by 1 desc)
where rownum<=:N )
order by sal )
where rownum=1;
select MAX(Salary) from Employee WHERE Salary NOT IN (select MAX(Salary) from Employee );
Simple way WITHOUT using any special feature specific to Oracle, MySQL etc.
Suppose EMPLOYEE table has data as below. Salaries can be repeated.
By manual analysis we can decide ranks as follows :-
Same result can be achieved by query
select *
from (
select tout.sal, id, (select count(*) +1 from (select distinct(sal) distsal from
EMPLOYEE ) where distsal >tout.sal) as rank from EMPLOYEE tout
) result
order by rank
First we find out distinct salaries.
Then we find out count of distinct salaries greater than each row.
This is nothing but the rank of that id.
For highest salary, this count will be zero. So '+1' is done to start rank from 1.
Now we can get IDs at Nth rank by adding where clause to above query.
select *
from (
select tout.sal, id, (select count(*) +1 from (select distinct(sal) distsal from
EMPLOYEE ) where distsal >tout.sal) as rank from EMPLOYEE tout
) result
where rank = N;
The simple way is to use OFFSET. Not only second, any position we can query using offset.
SELECT SALARY,NAME FROM EMPLOYEE ORDER BY SALARY DESC LIMIT 1 OFFSET 1 --Second largest
SELECT SALARY,NAME FROM EMPLOYEE ORDER BY SALARY DESC LIMIT 1 OFFSET 9 --For 10th largest
I think you would want to use DENSE_RANK as you don't know how many employees have the same salary and you did say you wanted nameS of employees.
CREATE TABLE #Test
(
Id INT,
Name NVARCHAR(12),
Salary MONEY
)
SELECT x.Name, x.Salary
FROM
(
SELECT Name, Salary, DENSE_RANK() OVER (ORDER BY Salary DESC) as Rnk
FROM #Test
) x
WHERE x.Rnk = 2
ROW_NUMBER would give you unique numbering even if the salaries tied, and plain RANK would not give you a '2' as a rank if you had multiple people tying for highest salary. I've corrected this as DENSE_RANK does the best job for this.
Below query can be used to find the nth maximum value, just replace 2 from nth number
select * from emp e1 where 2 =(select count(distinct(salary)) from emp e2
where e2.emp >= e1.emp)
Here I used two queries for the following scenarios which are asked during an interview
First scenario:
Find all second highest salary in the table (Second highest salary with more than
one employee )
select * from emp where salary
In (select MAX(salary) from emp where salary NOT IN (Select MAX(salary) from
emp));
Second scenario:
Find only the second highest salary in the table
select min(temp.salary) from (select * from emp order by salary desc limit 2)
temp;
There are two way to do this first:
Use subquery to find the 2nd highest
SELECT MAX(salary) FROM employees
WHERE salary NOT IN (
SELECT MAX (salary) FROM employees)
But this solution is not much good as if you need to find out the 10 or 100th highest then you may be in trouble. So instead go for window function like
select * from
(
select salary,ROW_NUMBER() over(
order by Salary desc) as
rownum from employees
) as t where t.rownum=2
By using this method you can find out nth highest salary without any trouble.
select * from emp where salary = (
select salary from
(select ROW_NUMBER() over (order by salary) as 'rownum', *
from emp) t -- Order employees according to salary
where rownum = 2 -- Get the second highest salary
)
select max(age) from yd where age<(select max(age) from HK) ; /// True two table Highest
SELECT * FROM HK E1 WHERE 1 =(SELECT COUNT(DISTINCT age) FROM HK E2 WHERE E1.age < E2.age); ///Second Hightest age RT single table
select age from hk e1 where (3-1) = (select count(distinct (e2.age)) from yd e2 where e2.age>e1.age);//// same True Second Hight age RT two table
select max(age) from YD where age not in (select max(age) from YD); //second hight age in single table
Can we also use
select e2.max(sal), e2.name
from emp e2
where (e2.sal <(Select max (Salary) from empo el))
group by e2.name
Please let me know what is wrong with this approach
SELECT *
FROM TABLE1 AS A
WHERE NTH HIGHEST NO.(SELECT COUNT(ATTRIBUTE) FROM TABLE1 AS B) WHERE B.ATTRIBUTE=A.ATTRIBUTE;
this is the simple query .. if u want the second minimum then just change the max to min and change the less than(<) sign to grater than(>).
select max(column_name) from table_name where column_name<(select max(column_name) from table_name)
SELECT name
FROM employee
WHERE salary =
(SELECT MIN(salary)
FROM (SELECT TOP (2) salary
FROM employee
ORDER BY salary DESC) )
SELECT MAX(Salary) FROM Employee
WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee)
If you want to display the name of the employee who is getting the second highest salary then use this:
SELECT employee_name
FROM employee
WHERE salary = (SELECT max(salary)
FROM employee
WHERE salary < (SELECT max(salary)
FROM employee);
Try This one
select * from
(
select name,salary,ROW_NUMBER() over( order by Salary desc) as
rownum from employee
) as t where t.rownum=2
http://askme.indianyouth.info/details/write-a-sql-query-to-find-the-10th-highest-employee-salary-from-an-employee-table-explain-your-answer-111
Try this to get the respective nth highest salary.
SELECT
*
FROM
emp e1
WHERE
2 = (
SELECT
COUNT(salary)
FROM
emp e2
WHERE
e2.salary >= e1.salary
)
Select * from employee where salary = (Select max(salary) from employee where salary not in(Select max(salary)from employee))
Explanation :
Query 1 : Select max(salary) from employee where salary not in(Select max(salary) from employee) - This query will retrieve second highest salary
Query 2 : Select * from employee where salary=(Query 1) - This query will retrieve all the records having second highest salary(Second highest salary may have multiple records)
I think this is probably the simplest out of the lot.
SELECT Name FROM Employees group BY Salary DESCENDING limit 2;
Try this: This will give dynamic results irrespective of no of rows
SELECT * FROM emp WHERE salary = (SELECT max(e1.salary)
FROM emp e1 WHERE e1.salary < (SELECT Max(e2.salary) FROM emp e2))**
Here's a simple approach:
select name
from employee
where salary=(select max(salary)
from(select salary from employee
minus
select max(salary) from employee));
I want to post here possibly easiest solution. It worked in mysql.
Please check at your end too:
SELECT name
FROM `emp`
WHERE salary = (
SELECT salary
FROM emp e
ORDER BY salary DESC
LIMIT 1
OFFSET 1
declare
cntr number :=0;
cursor c1 is
select salary from employees order by salary desc;
z c1%rowtype;
begin
open c1;
fetch c1 into z;
while (c1%found) and (cntr <= 1) loop
cntr := cntr + 1;
fetch c1 into z;
dbms_output.put_line(z.salary);
end loop;
end;
Using this SQL, Second highest salary will get with Employee Name
Select top 1 start at 2 salary from employee group by salary order by salary desc;
How can I get id of department in which employees receive the maximum salary:
Employee table: Empl (ID, FirstName, LastName, Salary, DeptId)
Departments table: Dept (ID, City)
rus (Вывести “id” подразделения, в котором сотрудники получают максимальную заработную плату.)
EDIT: Changed SUM(Salary) to AVG(Salary) based on comments on the question.
SELECT TOP 1 DeptId
FROM Employees
GROUP BY DeptId
ORDER BY AVG(Salary) DESC
SELECT TOP 1 B.*
FROM (SELECT DeptId, AVG(Salary) AvgSalary
FROM Empl
GROUP BY DeptId) A
INNER JOIN Dept B
ON A.DeptId = B.Id
ORDER BY AvgSalary DESC
To get the one single Department's ID where the highest single salary is paid:
SELECT TOP 1 DeptID
FROM dbo.Empl
ORDER BY Salary DESC
Or are you looking for something else?
I would assume you mean max average salary of a department and not the single highest salary across all departments.
However it seems all you would have to do is use the following SQL functions
MAX function
AVG function
group by department ID and viola.
Thought I agree with the comments above, I will assume you are doing this for research ;-)
select id
from dept
where id = ( select deptid
from ( select max(avg_salary), deptid
from ( select deptid, avg(salary) as avg_salary
from empl
group by deptid )
group by deptid )
)
:-)
SELECT DepartmentId
FROM Employee
WHERE Salary = (SELECT MAX(Salary) FROM Employee)
what is the query to return Name and Salary of employee Having Max Salary
SELECT Name, Salary FROM Minions
WHERE Salary = (SELECT Max(Salary) FROM Minions)
Note that this will return more than one row if there is more than one employee who have the same max salary
select name, salary from (select * from salary_table order by salary desc limit 1)
SELECT FirstName, max(salary)
FROM Employees
WHERE salary = (
SELECT max(salary)
FROM employees
)
GROUP BY FirstName
working in SQL SERVER 2012
A couple of proprietary solutions
SELECT TOP 1 [WITH ties] Name, Salary
FROM employee
ORDER BY Salary DESC
SELECT Name, Salary
FROM employee
ORDER BY Salary DESC
LIMIT 1
And a standard one
WITH E AS
(
SELECT Name, Salary,
ROW_NUMBER() OVER (ORDER BY Salary DESC) RN /*Or RANK() for ties*/
FROM employee
)
SELECT Name, Salary FROM E WHERE RN=1
In case there are multiple rows with the same MAX number then you can just limit the number to desired number like this
SELECT Name, Salary FROM Minions
WHERE Salary = (SELECT Max(Salary) FROM Minions) LIMIT 1
Select e.name, e.salary from employee e where
not exists (select salary from employee e1 where e.salary < e1.salary)
This will of course return more than one record if there are multiple people with the max salary.
If you are using an oracle database and only want a single "employee" then:
SELECT MAX( name ) KEEP ( DENSE_RANK LAST ORDER BY salary ASC ) AS name,
MAX( salary ) KEEP ( DENSE_RANK LAST ORDER BY salary ASC ) AS salary
FROM Minions;
SQLFIDDLE
(kudos to Neil N for his table name)
SQL Server has a similar FIRST_VALUE (or LAST_VALUE) analytic function.
PostgreSQL also supports window functions including LAST_VALUE.
These type of queries (grouped operaions) can execute with sub query.
Example
select *from emp where sal=(max(sal)from emp)
Assuming only one employee has maximum salary
SQL Server:
select top 1 name, salary
from employee
order by salary desc
Oracle:
select name, salary
from employee
order by salary desc
limit 1
Above queries scans the table only once unlike other queries using subqueries.
