Here is a query from Northwind database that shows it is possible to do that:

select
SUM(productid) as sum1
,SUM(unitprice) as sum2
from dbo.[Order Details]

I read almost all the post about how to find the Nth largest salary from a table. I want to create a function that takes two parameters
1. column name.
2. value of “n”.
and this return the nth highest salary. I googled it like a million and a half times but I reached nowhere.

I think this can be done using Aggregate functions. i want to know how to create aggregate function?? please help me out.

I have a small query regarding the usage of Aggregate functions with Union or Union All command. It would be great if som1 can help me out.

SELECT TYPE, DATEDIFF(HH,CREATE_DATE,END_DATE) AS DURATION
FROM TABLE1
WHERE TAG IN (‘A’,'B’,'F’,'X’)

UNION ALL

SELECT TYPE, DATEDIFF(HH,CREATE_DATE,END_DATE) AS DURATION
FROM TABLE2
WHERE TAG IN (‘C’,'J’)

Using the above code I am able to get the results from both the tables but I want the AVERAGE of the DURATION from the result set for a particular TYPE.
