Greetings!
I am trying to compress a table in my database, but for some reason the
compression doesn't work.

Here are the executed commands and their results:

DB20000I  The SQL command completed successfully.

DB20000I  The REORG command completed successfully.

AVGROWSIZE AVGCOMPRESSEDROWSIZE PCTPAGESSAVED AVGROWCOMPRESSIONRATIO
PCTROWSCOMPRESSED
---------- -------------------- ------------- ------------------------ ------------------------
      223                    0             0            +0,00000E+000
+0,00000E+000

The table itself is range partitioned (by the date column "dat_val")
(allthough this shouldn't affect the row compression), and there are
alltogether five partitions:
DATAPARTITIONNAME     DATAPARTITIONID     PARTITIONOBJECTID
TR_GEN_INSTR_2002         0                                       4
TR_GEN_INSTR_2003         1                                       5
TR_GEN_INSTR_2004         2                                       6
TR_GEN_INSTR_2005         3                                       7
TR_GEN_INSTR_2006         4                                       8

The INSPECT ROWCOMPESTIMATE command shows something rather strange:
-all is fine for the above five partitions, with space savings estimated
around 80%, but then the command output mentions another three table objects
with IDs 9,10 and 11 for which it says that "No dictionary can be built as
row compression is not supported for this table". These objects don't exist,
nor do I see them in the SYSCAT.DATAPARTITIONS view...

What is happening here??

Thanks for any help,
