Derived Column with Rank and Qualify

[Novs]

I am using teradata.

This is what I want to do:

SELECT

'Total ' as Row_One
, Name
, Sum (Column2) Column2_Sum
, Sum (Column3) Column3_Sum
, Sum (Column4) Column4_Sum
, (Column2_Sum + Column3_Sum + Column4_Sum) Total_Sum
, Rank (Total_Sum) Total_Sum_Rank

FROM

GROUP BY Name

ORDER BY Total_Sum DESC

Qualify Total_Sum_Rank <= 10

i know this code won't work because you can't + in a select. how can i duplicate the logic?

Try this :
SELECT 'Total ' AS Row_One
, Name
, Column2_Sum
, Column3_Sum
, Column4_Sum
, Total_Sum
, RANK(Total_Sum) Total_Sum_Rank
FROM
( SELECT Name
, SUM (Column2) AS Column2_Sum
, SUM (Column3) AS Column3_Sum
, SUM (Column4) AS Column4_Sum
, (Column2_Sum + Column3_Sum + Column4_Sum) Total_Sum
FROM

GROUP BY Name
)
ORDER BY Total_Sum DESC
QUALIFY Total_Sum_Rank <= 10
;

thanks a lot. Your fix looks excellent. I try to run it, but teradata gives me a 'expecting something like a UDFCALLNAME keyword error between the ) and ORDER. So now I need to work that out. Also, I changed the name of the first column from ROW_ONE to COLUMN_ONE and tried adding that column to the subquery.

so it looks like this:

SELECT 'Total ' AS Column_One
, Name
, Column2_Sum
, Column3_Sum
, Column4_Sum
, Total_Sum
, RANK(Total_Sum) Total_Sum_Rank
FROM
( SELECT 'Total ' AS Column_One
, Name
, SUM (Column2) AS Column2_Sum
, SUM (Column3) AS Column3_Sum
, SUM (Column4) AS Column4_Sum
, (Column2_Sum + Column3_Sum + Column4_Sum) Total_Sum
FROM

GROUP BY Name
)
ORDER BY Total_Sum DESC
QUALIFY Total_Sum_Rank <= 10
;

i'll tinker with it some more.

I'm confused...
I forgot to give a name to the derived table.
Only add "as XXX" between ")" and "ORDER" and it will be fixed !
