I have a problem, where i am required to determine a Rank on a table on the basis of a derived column. Say first column desired is Name of Port, 2nd column is the sum of profit made on that port. The third column should be the rank based on the highest profit the port has. How can i create an sql query of rank on a derived column like the sum of total profit for each port? Hopefully you can give a suitable example.

If we have 3 employees with second highest paid salary, we will get Salary three times in the result CTE. In order to avoid such kind of duplicate salaries, we can use either "top 1" or "distinct" keyword in the final select query.
Hi Venkat, Am very happy to see your videos. i have a small doubt in this video with the below query. with Result as ( select salary, RANK() over (order by salary desc) as salaryrank from [dbo].[dense_employees] ) SELECT TOP 1 salary from Result where salaryrank=1 and my table structure is: CREATE TABLE [dbo].[dense_employees]( [id] [int] NULL, [name] [varchar](30) NULL, [gender] [varchar](10) NULL, [salary] [int] NULL ) ON [PRIMARY] when am executing the above query in 2012 sql server its not giving output.its showing that "incorrect syntax near result". Please guide me how to execute this in 2012 sqlserver. it will be great if can you can help on this. when am browsing the internet some sites showing "with result sets" other than "with result as" Please guide me on this . Thnaks, Krishna
What is with this fake accent man? It makes it so hard to focus on the lesson without getting irritated out of your mind. Who are you? Priyanka Chopra?

Thank you Venkat. I need some more information on this with join condition. Example i have employee table which has eno,ename,esal,edeptno columns, and another table (dept) which has dno,dname. Now i want to get the second max salary of "dname='Maths'". Please help me on this.
With EmployeeCTE as ( select emp.Name as [Employee Name], Gender, Salary, dept.Name as [Department Name], Dense_Rank() over (partition by dept.Name order by Salary desc) DenseRank from tblEmployees emp inner join tblDepartment dept on emp.DepartmentId = dept.DepartmentId ) Select Salary from EmployeeCTE where DenseRank = 2 and [Department Name]='Maths' With the above inner query in EmployeeCTE, we will get all the employee details like Employee Name, Gender, Salary, Department Name and Dense Rank partitioned by each department. Finally, we are getting second highest paid salary for the department "Maths" from the EmployeeCTE.
