Hi Daniel,

As Bryan said, some work is being done to clean up the row_number syntax. In addition, it looks like the simpler, alternative FETCH/OFFSET syntax will probably make it into 10.5: https://issues.apache.org/jira/browse/DERBY-4079

Hi all.

I'm trying to use ROW_NUMBER() in conjunction with ORDER BY and not having a lot of luck.

This is the query I'm using, which I found on the Derby wiki:

  SELECT * FROM (
    SELECT ROW_NUMBER() OVER(ORDER BY startdate ASC) AS row,
           id, startdate, enddate, ...
    FROM HistoryRecord
  ) AS tmp
  WHERE row >= ? AND row < ?

I have also tried what I consider to be the intuitive way:

  SELECT * FROM (
    SELECT ROW_NUMBER() OVER() AS row, id, startdate, enddate, ...
    FROM HistoryRecord
    ORDER BY startdate ASC
  ) AS tmp
  WHERE row >= ? AND row < ?

Both of these give an error at ORDER BY. Am I doing something wrong, or is this a missing part of the ROW_NUMBER() feature?

Daniel
