Hi All,

When running this query I don't understand why there are more distinct
values than rows.

SELECT column_name, current_rows, number_distinct_values
FROM syscolumnstat
WHERE table_schema = 'QS36F'
AND table_name = 'CUSMASP'
AND column_name = 'CMCUS#';

COLUMN_NAME CURRENT_ROWS NUMBER_DISTINCT_VALUES
CMCUS# 716 724
I've tried searching on Google and the IBM site but couldn't find any
explanation.

Has anyone seen this and can explain it?

Thanks,

Rob
