We are going to discuss very important Topic which usually asks in the Interviews.
We will create the required query step by step-
select * from Employee_Master
Firstly we need to specify what will be the output, for this we need to apply Desc order in select query, this query arrange all the records of table in Descending Order on the Behalf of Salary.
select * from Employee_Master order by Salary desc
Since We Need to find out Nth Highest salary(3rd),We will apply TOP keyword in last query.
select top(3) * from Employee_Master order by Salary desc
With the help of this output we can identify that what Should be the 3rd Highest salary .It will be 6000 which belongs to Employee Sagar, Because we have already selected Top 3 after applying Descending Order in select query.
Now we need to Generate query for desired output.
We will use last query as Sub-Query and apply SELECT query on this subquery after that apply ASC order and apply TOP(1) on this query , it will generate desired output like that.
Select Top(1)* from (select top(3) * from Employee_Master order by Salary desc) as Employee_Master order by Salary asc
