  Peter,

  You can do it with CTE like this

  WITH x As (select row_number() over (partition by id1, id2 order by id2) nr FROM MyTab)

  delete FROM x where nr > 1

  Thanks,

  Oded

  Thanks, Oded.

  Unfortunately the CTE method does not work with SQL 2000. Last year I needed to cleanup hundreds tables in order to introduce primary keys, before 2000 - 2005 conversion and my method worked pretty well.

  Regards,

  Peter
