      Description

      select max(dnumbertables23008) from factsqlengineam_vec_orc where ddate = "2013-01-08 00:00:00";

      result: 241012

      select max(dnumbertables23008) from factsqlengineam_orc where ddate = "2013-01-08 00:00:00";

      result: 1052436

      Result is also 1052436 for text version of table.

      Also, for this query:

      select ddate, max(dnumbertables23008) from factsqlengineam_vec_orc group by ddate;

      the MAX result is correct for all ddate values (about 365 of them) except for ddate = "2013-01-08 00:00:00", when compared with the result for text.

      Let me know if you need help to set up this repro.
