AW: Some OLAP function perhaps?

["Birgitta Hauser" <Hauser@xxxxxxxxxxxxxxx>]

Try something like this:

With x as (Select Library, Object, Size, 
                  Dense_Rank() Over(Partition By Library Order By Size Desc)
as Rank
           From YourFile)
Select Library, Object, Size
Form x
Where Rank <= 10
Order By Library, Size Desc, Object;;


Mit freundlichen Grüßen / Best regards

Betreff: Some OLAP function perhaps?

I want to generate results like the following from a table with those 
columns, however, the summary row does not exist.  And, of the detail, I 
only want the 10 largest rows per library.

Library  Object  Size
BIGLIB           456789
BIGLIB   BIGOBJ  200000
BIGLIB   MEDOBJ  100000
BIGLIB   SMLOBJ   50000
...
MEDLIB           322457
MEDLIB   BIGOBJ  150492
MEDLIB   MEDOBJ   54329
MEDLIB   SMLOBJ   12222
...
SMLLIB           105298
SMLLIB   BIGOBJ  102201
