What is the simplest SQL Query to find the second largest value?
SqlPuzzleSql Problem Overview
What is the simplest SQL query to find the second largest integer value in a specific column?
There are maybe duplicate values in the column.
Sql Solutions
Solution 1 - Sql
SELECT MAX( col )
FROM table
WHERE col < ( SELECT MAX( col )
FROM table )
Solution 2 - Sql
SELECT MAX(col)
FROM table
WHERE col NOT IN ( SELECT MAX(col)
FROM table
);
Solution 3 - Sql
In T-Sql there are two ways:
--filter out the max
select max( col )
from [table]
where col < (
select max( col )
from [table] )
--sort top two then bottom one
select top 1 col
from (
select top 2 col
from [table]
order by col) topTwo
order by col desc
In Microsoft SQL the first way is twice as fast as the second, even if the column in question is clustered.
This is because the sort operation is relatively slow compared to the table or index scan that the max aggregation uses.
Alternatively, in Microsoft SQL 2005 and above you can use the ROW_NUMBER() function:
select col
from (
select ROW_NUMBER() over (order by col asc) as 'rowNum', col
from [table] ) withRowNum
where rowNum = 2

I see both some SQL Server specific and some MySQL specific solutions here, so you might want to clarify which database you need. Though if I had to guess I'd say SQL Server since this is trivial in MySQL.
I also see some solutions that won't work because they fail to take into account the possibility for duplicates, so be careful which ones you accept. Finally, I see a few that will work but that will make two complete scans of the table. You want to make sure the 2nd scan is only looking at 2 values.
SQL Server (pre-2012):
SELECT MIN([column]) AS [column]
FROM (
SELECT TOP 2 [column]
FROM [Table]
GROUP BY [column]
ORDER BY [column] DESC
) a
MySQL:
SELECT `column`
FROM `table`
GROUP BY `column`
ORDER BY `column` DESC
LIMIT 1,1
Update:
SQL Server 2012 now supports a much cleaner (and standard) OFFSET/FETCH syntax:
SELECT [column]
FROM [Table]
GROUP BY [column]
ORDER BY [column] DESC
OFFSET 1 ROWS
FETCH NEXT 1 ROWS ONLY;
Solution 5 - Sql
I suppose you can do something like:
SELECT *
FROM Table
ORDER BY NumericalColumn DESC
LIMIT 1 OFFSET 1
or
SELECT *
FROM Table ORDER BY NumericalColumn DESC
LIMIT (1, 1)
depending on your database server. Hint: SQL Server doesn't do LIMIT.
Solution 6 - Sql
The easiest would be to get the second value from this result set in the application:
SELECT DISTINCT value
FROM Table
ORDER BY value DESC
LIMIT 2
But if you must select the second value using SQL, how about:
SELECT MIN(value)
FROM ( SELECT DISTINCT value
FROM Table
ORDER BY value DESC
LIMIT 2
) AS t
Solution 7 - Sql
A very simple query to find the second largest value
SELECT `Column`
FROM `Table`
ORDER BY `Column` DESC
LIMIT 1,1;
Solution 8 - Sql
you can find the second largest value of column by using the following query
SELECT *
FROM TableName a
WHERE
2 = (SELECT count(DISTINCT(b.ColumnName))
FROM TableName b WHERE
a.ColumnName <= b.ColumnName);
you can find more details on the following link

Solution 9 - Sql
MSSQL
SELECT *
FROM [Users]
order by UserId desc OFFSET 1 ROW
FETCH NEXT 1 ROW ONLY;
MySQL
SELECT *
FROM Users
order by UserId desc LIMIT 1 OFFSET 1
No need of sub queries ... just skip one row and select second rows after order by descending
Solution 10 - Sql
SELECT MAX(Salary)
FROM Employee
WHERE Salary NOT IN ( SELECT MAX(Salary)
FROM Employee
)
This query will return the maximum salary, from the result - which not contains maximum salary from overall table.
Solution 11 - Sql
Old question I know, but this gave me a better exec plan:
SELECT TOP 1 LEAD(MAX (column)) OVER (ORDER BY column desc)
FROM TABLE
GROUP BY column
Solution 12 - Sql
This is very simple code, you can try this :-
ex : Table name = test
salary
1000
1500
1450
7500
MSSQL Code to get 2nd largest value
select salary from test order by salary desc offset 1 rows fetch next 1 rows only;
here 'offset 1 rows' means 2nd row of table and 'fetch next 1 rows only' is for show only that 1 row. if you dont use 'fetch next 1 rows only' then it shows all the rows from the second row.
Solution 13 - Sql
select * from (select ROW_NUMBER() over (Order by Col_x desc) as Row, Col_1
from table_1)as table_new tn inner join table_1 t1
on tn.col_1 = t1.col_1
where row = 2
Hope this help to get the value for any row.....
Solution 14 - Sql
Use this query.
SELECT MAX( colname )
FROM Tablename
where colname < (
SELECT MAX( colname )
FROM Tablename)
Solution 15 - Sql
Simplest of all
select sal
from salary
order by sal desc
limit 1 offset 1
Solution 16 - Sql
Tom, believe this will fail when there is more than one value returned in select max([COLUMN_NAME]) from [TABLE_NAME] section. i.e. where there are more than 2 values in the data set.
Slight modification to your query will work -
select max([COLUMN_NAME])
from [TABLE_NAME]
where [COLUMN_NAME] IN ( select max([COLUMN_NAME])
from [TABLE_NAME]
)
Solution 17 - Sql
select max(COL_NAME)
from TABLE_NAME
where COL_NAME in ( select COL_NAME
from TABLE_NAME
where COL_NAME < ( select max(COL_NAME)
from TABLE_NAME
)
);
subquery returns all values other than the largest. select the max value from the returned list.
Solution 18 - Sql
select min(sal) from emp where sal in
(select TOP 2 (sal) from emp order by sal desc)
Note
sal is col name
emp is table name
Solution 19 - Sql
select col_name
from (
select dense_rank() over (order by col_name desc) as 'rank', col_name
from table_name ) withrank
where rank = 2
Solution 20 - Sql
SELECT
*
FROM
table
WHERE
column < (SELECT max(columnq) FROM table)
ORDER BY
column DESC LIMIT 1
Solution 21 - Sql
This is an another way to find the second largest value of a column.Consider the table 'Student' and column 'Age'.Then the query is,
select top 1 Age
from Student
where Age in ( select distinct top 2 Age
from Student order by Age desc
) order by Age asc
Solution 22 - Sql
It is the most esiest way:
SELECT
Column name
FROM
Table name
ORDER BY
Column name DESC
LIMIT 1,1
Solution 23 - Sql
select age
from student
group by id having age< ( select max(age)
from student
)
order by age
limit 1
Solution 24 - Sql
As you mentioned duplicate values . In such case you may use DISTINCT and GROUP BY to find out second highest value
Here is a table
> salary
:
> GROUP BY
SELECT amount FROM salary
GROUP by amount
ORDER BY amount DESC
LIMIT 1 , 1
> DISTINCT
SELECT DISTINCT amount
FROM salary
ORDER BY amount DESC
LIMIT 1 , 1
First portion of LIMIT = starting index
Second portion of LIMIT = how many value
Solution 25 - Sql
SELECT MAX(sal)
FROM emp
WHERE sal NOT IN ( SELECT top 3 sal
FROM emp order by sal desc
)
this will return the third highest sal of emp table
Solution 26 - Sql
select max(column_name)
from table_name
where column_name not in ( select max(column_name)
from table_name
);
not in is a condition that exclude the highest value of column_name.

Solution 27 - Sql
select top 1 MyIntColumn from MyTable
where
MyIntColumn <> (select top 1 MyIntColumn from MyTable order by MyIntColumn desc)
order by MyIntColumn desc
Solution 28 - Sql
This works in MS SQL:
select max([COLUMN_NAME]) from [TABLE_NAME] where [COLUMN_NAME] <
( select max([COLUMN_NAME]) from [TABLE_NAME] )
Solution 29 - Sql
Something like this? I haven't tested it, though:
select top 1 x
from (
select top 2 distinct x
from y
order by x desc
) z
order by x
Solution 30 - Sql
See https://stackoverflow.com/questions/16568.
Sybase SQL Anywhere supports:
SELECT TOP 1 START AT 2 value from table ORDER BY value
Solution 31 - Sql
select * from emp e where 3>=(select count(distinct salary)
from emp where s.salary<=salary)
This query selects the maximum three salaries. If two emp get the same salary this does not affect the query.
Solution 32 - Sql
Using a correlated query:
Select * from x x1 where 1 = (select count(*) from x where x1.a < a)
Solution 33 - Sql
Query to find the 2nd highest number in a row-
select Top 1 (salary) from XYZ
where Salary not in (select distinct TOP 1(salary) from XYZ order by Salary desc)
ORDER BY Salary DESC
By changing the highlighted Top 1 to TOP 2, 3 or 4 u can find the 3rd, 4th and 5th highest respectively.
Solution 34 - Sql
We can also make use of order by and top 1 element as follows:
Select top 1 col_name from table_name
where col_name < (Select top 1 col_name from table_name order by col_name desc)
order by col_name desc
Solution 35 - Sql
SELECT * FROM EMP
WHERE salary=
(SELECT MAX(salary) FROM EMP
WHERE salary != (SELECT MAX(salary) FROM EMP)
);
Solution 36 - Sql
Try:
select a.* ,b.* from
(select * from (select ROW_NUMBER() OVER(ORDER BY fc_amount desc) SrNo1, fc_amount as amount1 From entry group by fc_amount) tbl where tbl.SrNo1 = 2) a
,
(select * from (select ROW_NUMBER() OVER(ORDER BY fc_amount asc) SrNo2, fc_amount as amount2 From entry group by fc_amount) tbl where tbl.SrNo2 =2) b
Solution 37 - Sql
select * from [table] where (column)=(select max(column)from [table] where column < (select max(column)from [table]))
Solution 38 - Sql
select MAX(salary) as SecondMax from test where salary !=(select MAX(salary) from test)
Solution 39 - Sql
select score
from table
where score = (select max(score)-1 from table)
Solution 40 - Sql
Microsoft SQL Server - Using Two TOPs for the N-th highest value (aliased sub-query).
To solve for the 2nd highest:
SELECT TOP 1 q.*
FROM (SELECT TOP 2 column_name FROM table_name ORDER BY column_name DESC) as q
ORDER BY column_name ASC;
Uses TOP twice, but requires an aliased sub-query. Essentially, the inner query takes the greatest 2 values in descending order, then the outer query flips in ascending order so that 2nd highest is now on top. The SELECT statement returns this top.
To solve for the n-th highest value modify the sub-query TOP value. For example:
SELECT TOP 1 q.*
FROM (SELECT TOP 5 column_name FROM table_name ORDER BY column_name DESC) as q
ORDER BY column_name;
Would return the 5th highest value.

select extension from [dbo].[Employees] order by extension desc offset 2 rows fetch next 1 rows only
Solution 42 - Sql
Very Simple. The distinct keyword will take care of duplicates as well.
SELECT distinct SupplierID FROM [Products] order by SupplierID desc limit 1 offset 1
Solution 43 - Sql
The easiest way to get second last row from a SQL table is to use ORDER BY ColumnName DESC and set LIMIT 1,1.
Try this:
SELECT * from `TableName` ORDER BY `ColumnName` DESC LIMIT 1,1
Solution 44 - Sql
SELECT * FROM `employee` WHERE employee_salary = (SELECT employee_salary
FROM`employee` GROUP BY employee_salary ORDER BY employee_salary DESC LIMIT
1,1)
Solution 45 - Sql
You can find nth highest value using the following query.
select top 1 UnitPrice from (select distinct top n UnitPrice from
[Order Details] order by UnitPrice desc) as Result order by UnitPrice asc
Here, the value of n will be 1 (for the highest number), 2 (for the second highest number), 3 (for the third highest number)...
Solution 46 - Sql
At first make a dummy table without max salary then query max value from dummy table
SELECT max(salary) from (Select * FROM emp WHERE salary<> (SELECT MAX(salary) from emp)) temp
