Suppose that you are given the following simple database table called Employee that has 2 columns named Employee ID and Salary:
Employee
Employee ID Salary
3 200
4 800
7 450
I wish to write a query select max(salary) as max_salary, 2nd_max_salary from employee
then it should return
max_salary 2nd_max_salary
800 450
i know how to find 2nd highest salary
SELECT MAX(Salary) FROM Employee
WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee )
or to find the nth
SELECT FROM Employee Emp1 WHERE (N-1) = ( SELECT COUNT(DISTINCT(Emp2.Salary)) FROM Employee Emp2
WHERE Emp2.Salary > Emp1.Salary)
but i am unable to figureout how to join these 2 results for the desired result
This solution will give all employee name and salary who have second highest salary
SELECT name, salary
FROM employee
WHERE salary = (
SELECT
salary
FROM employee AS emp
ORDER BY salary DESC
LIMIT 1,1
);
$q="select * from info order by salary desc limit 1,0"; // display highest 2 salary
or
$q="select * from info order by salary desc limit 1,0"; // display 2nd highest salary
If we want to find Employee that gets 3nd highest salary then execute this query
SELECT a.employeeid,
a.salary
FROM (SELECT employeeid,
salary,
Dense_rank()
OVER(
ORDER BY salary) AS n
FROM employee) AS a
WHERE n = 3
What do you want
without nested query
select max(e.salary) as max_salary, max(e1.salary) as 2nd_max_salary
from employee as e
left join employee as e1 on e.salary != e1.salary
group by e.salary desc limit 1;
Highest 3 Salaries in mysql
SELECT Salary FROM (SELECT DISTINCT Salary FROM Employee ORDER BY Salary desc) AS custom LIMIT 3;
Highest n Salaries in mysql, just put the value of n
SELECT Salary FROM (SELECT DISTINCT Salary FROM Employee ORDER BY Salary desc) AS custom LIMIT n;
Find Max salary of an employee
SELECT MAX(Salary) FROM Employee
Find Second Highest Salary
SELECT MAX(Salary) FROM Employee
Where Salary Not In (Select MAX(Salary) FROM Employee)
OR
SELECT MAX(Salary) FROM Employee
WHERE Salary <> (SELECT MAX(Salary) FROM Employee )
`select max(salary) as first, (select salary from employee order by salary desc limit 1, 1) as second from employee limit 1`
For max salary simply we can use max function, but second max salary we should use sub query. in sub query we can use where condition to check second max salary or simply we can use limit.
Try like this
SELECT (select max(Salary) from Employee) as MAXinmum),(max(salary) FROM Employee WHERE salary NOT IN (SELECT max(salary)) FROM Employee);
(Or)
Try this, n would be the nth item you would want to return
SELECT DISTINCT(Salary) FROM table ORDER BY Salary DESC LIMIT n,1
In your case
SELECT DISTINCT(column_name) FROM table_name ORDER BY column_name DESC limit 2,1;
Max Salary:
select max(salary) from tbl_employee <br><br>
Second Max Salary:
select max(salary) from tbl_employee where salary < ( select max(salary) from tbl_employee);
Here change n value according your requirement:
SELECT top 1 amount
FROM (
SELECT DISTINCT top n amount
FROM payment
ORDER BY amount DESC ) AS temp
ORDER BY amount
Here is another solution which uses sub query but instead of IN clause it uses < operator
SELECT MAX(Salary) From Employees WHERE Salary < ( SELECT Max(Salary) FROM Employees);
select * from
Employees where Sal >=
(SELECT
max(Sal)
FROM
Employees
WHERE
Sal < (
SELECT
max(Sal)
FROM
Employees;
));
Try below Query, was working for me to find Nth highest number salary. Just replace your number with nth_No
Select DISTINCT TOP 1 salary
from
(Select DISTINCT TOP *nth_No* salary
from Employee
ORDER BY Salary DESC)
Result
ORDER BY Salary
select
e.salary
from(
SELECT * FROM
Employee
group by salary
order by salary desc
limit 2
) e
order by salary asc
limit 1;
For second highest salary, This one work for me:
SELECT salary
FROM employee
WHERE salary
NOT IN (
SELECT MAX( salary )
FROM employee
ORDER BY salary DESC
)
LIMIT 1
Not really a nice query but :
SELECT * from (
SELECT max(Salary) from Employee
) as a
LEFT OUTER JOIN
(SELECT MAX(Salary) FROM Employee
WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee )) as b
ON 1=1
i think that the simple way in oracle is this:
SELECT Salary FROM
(SELECT DISTINCT Salary FROM Employee ORDER BY Salary desc)
WHERE ROWNUM <= 2;
This should work same :
SELECT MAX(salary) max_salary,
(SELECT MAX(salary)
FROM Employee
WHERE salary NOT IN
(SELECT MAX(salary)
FROM Employee)) 2nd_max_salary
FROM Employee
select * from emp where sal =(select max(sal) from emp where eno in(select eno from emp where sal <(select max(sal)from emp )));
try the above code ....
if you want the third max record then add another nested query "select max(sal)from emp" inside the bracket of the last query and give less than operator in front of it.
The Best & Easiest solution:-
SELECT
max(salary)
FROM
salary
WHERE
salary < (
SELECT
max(salary)
FROM
salary
);
Try
SELECT
SUBSTRING( GROUP_CONCAT( Salary ), 1 , LOCATE(",", GROUP_CONCAT( Salary ) ) -1 ) AS max_salary,
SUBSTRING( GROUP_CONCAT( Salary ), LOCATE(",", GROUP_CONCAT( Salary ) ) +1 ) AS second_max_salary
FROM
(
SELECT Salary FROM `Employee` ORDER BY Salary DESC LIMIT 0,2
) a

Simplest way to fetch second max salary & nth salary
select
DISTINCT(salary)
from employee
order by salary desc
limit 1,1
Note:
limit 0,1 - Top max salary
limit 1,1 - Second max salary
limit 2,1 - Third max salary
limit 3,1 - Fourth max salary
with Common table expression
With cte as (
SELECT
ROW_NUMBER() Over (Order By Salary Desc) RowNumber,
Max(Salary) Salary
FROM
Employee
Group By Salary
)
Select * from cte where RowNumber = 2
You can write SQL query in any of your favorite database e.g. MySQL, Microsoft SQL Server or Oracle. You can also use database specific feature e.g. TOP, LIMIT or ROW_NUMBER to write SQL query, but you must also provide a generic solution which should work on all database. In fact, there are several ways to find second highest salary and you must know a couple of them e.g. in MySQL without using the LIMIT keyword, in SQL Server without using TOP and in Oracle without using RANK and ROWNUM.
Generic SQL query:
SELECT
MAX(salary)
FROM
Employee
WHERE
Salary NOT IN (
SELECT
Max(Salary)
FROM
Employee
);
Another solution which uses sub query instead of NOT IN clause. It uses < operator.
SELECT
MAX(Salary)
FROM
Employee
WHERE
Salary < (
SELECT
Max(Salary)
FROM
Employee
);
This is awesome Query to find the nth Maximum: For example: -
You want to find salary 8th row Salary, Just Changed the indexed value to 8.
Suppose you have 100 rows with Salary. Now you want to find Max salary for 90th row. Just changed the Indexed Value to 90.
set @n:=0;
select * from (select *, (@n:=@n+1) as indexed from employee order by Salary desc)t where t.indexed = 1;
I think, It is the simplest way to find MAX and second MAX Salary.You may try this way.
SELECT MAX(Salary) FROM Employee; -- For Maximum Salary.
SELECT MAX(Salary) FROM Employee WHERE Salary < (SELECT MAX(Salary) FROM Employee); -- For Second Maximum Salary
You can write 2 subqueries like this example
SELECT (select max(Salary) from Employee) as max_id,
(select Salary from Employee order by Salary desc limit 1,1) as max_2nd
try this
select max(salary) as first,
(select salary from employee order by salary desc limit 1, 1) as second
from employee limit 1
For unique salaries (i.e. first can't be same as second):
SELECT
MAX( s.salary ) AS max_salary,
(SELECT
MAX( salary )
FROM salaries
WHERE salary <> MAX( s.salary )
ORDER BY salary DESC
LIMIT 1
) AS 2nd_max_salary
FROM salaries s
And also because it's such an unnecessary way to go about solving this problem (Can anyone say 2 rows instead of 2 columns, LOL?)
Select Distinct sal From emp Order By sal Desc Limit 1,1;
It will take all Distinct sal. And Limit 1,1 means: leaves top one record and print 1 record.
This will work To find the nth maximum number
SELECT
TOP 1 * from (SELECT TOP nth_largest_no * FROM Products Order by price desc) ORDER BY price asc;
For Fifth Largest number
SELECT
TOP 1 * from (SELECT TOP 5 * FROM Products Order by price desc) ORDER BY price asc;
