      Description

      As part of implementing the overall OLAP Operations features of SQL (DERBY-581), implement the ROW_NUMBER() window function.

      More information about this feature is available at http://wiki.apache.org/db-derby/OLAPRowNumber

      DERBY-2998 implements

      • framework code for windows and window function result columns.
      • the ROW_NUMBER() window function according to SQL2003
        but the implementation is limited by
      • only supporting an empty, unnamed, inline window definition (i.e the full, unordered resultset)
      • not being fully optimized
