This works, thanks! But....sometimes there are query like this:

SELECT SUB.*
FROM ( DISTINCT select a.Field1, b.Field1,
row_number() over (Order by a.Field1)
FROM A inner join B on A.X = B.Y) SUB (New_Name, Field1_Too, Rnk)
WHERE rnk >= ? AND rnk < ?
Order By Rnk;

Since there is the rnk field in the sybquery now, some duplicated rows aren't filtered anymore. :-)

If you only want the first 5 (or 10 or whatever rows), you can specify FETCH
FIRST x ROWS ONLY at the end of your SELECT-Statement:

My previous post was incomplete: Activiti needs the LIMIT/OFFSET clause for paging poupouses.

Thanks.
