Dieter,

Here are the results of my tests:

     CREATE SET TABLE SYSDBA.dropme ,NO FALLBACK ,
          NO BEFORE JOURNAL,
          NO AFTER JOURNAL,
          CHECKSUM = DEFAULT
          (
           field1_integer INTEGER,
           field2_decimal DECIMAL(18,0),
           field3_ts TIMESTAMP(6))
     PRIMARY INDEX ( field1_integer );

     INSERT INTO dropme VALUES( 1, 123456789012345678., TIMESTAMP '2007-07-25
     21:24:03.540000+00:00');
     INSERT INTO dropme VALUES( 2, 234567890123456781., TIMESTAMP '2007-07-26
     21:24:03.540000+00:00');
     INSERT INTO dropme VALUES( 3, 345678901234567812., TIMESTAMP '2007-06-26
     21:24:03.540000+00:00');
     INSERT INTO dropme VALUES( 4, 456789012345678123., TIMESTAMP '2007-06-27
     21:24:03.540000+00:00');

     COLLECT STATS ON dropme COLUMN field3_ts;
     COLLECT STATS ON dropme COLUMN field2_decimal;
     COLLECT STATS ON dropme COLUMN field1_integer;

     SELECT ColumnName, SUBSTR(fieldstatistics, 1, 80) AS STATS FROM
     dbc.ColumnStats WHERE databasename = 'sysdba' AND tablename = 'dropme';

     ColumnName                      STATS
