Subj:   Re: Can the ROW_NUMBER data type be changed?
 
From:   td newsgroup

Hi,

seems not to work the same way - also to my surprise.

Table gutenberg has about 1.6 billion so I cross join with a 2 row result. Single node dev system with R14.0....

     select top 100 *
     from (
     select g.term_in_gutenberg, t.id, cast(row_number() over (order by g.term_in_gutenberg,
     t.id) as decimal(18,0)) as row_num from xxx.gutenberg g
           cross join
           (select id from yyy.ref_id where id in (1,2)) as t
     ) as t
     order by 3 desc
     ;

      *** Failure 2616 Numeric overflow occurred during computation.
                     Statement# 1, Info =0
      *** Total elapsed time was 2 hours, 24 minutes and 54 seconds.

Ulrich
