سؤال
I have got two cfquery result with same column name. I want to merge them in such a way that I remove the duplicates based on a particular colum.
So it should be like merge query 1 with query 2 where value of query1.column1 > query2.column1
Is there a way to get this done by MS SQL?
My resulteset is like this at the moment
|name |value| temp_id
test1 1 001
test1 2 001
test2 2 002
test2 1 002
I want to get the rows with distinct column (name) and higest value
So from above example I want
test1 with value 2 and test 2 with value 2

If you're only looking to get the name and the maximum value then you can just do
SELECT name, MAX(value) AS value
FROM yourtable
GROUP BY name
