Hi,
When statistics are updated with low keyword, information is not updated at sysdistrib table, hence no traces of timestamp is available. Keywords medium and high will generate columnwise data bins in distrib table.
Following SQL statement will show when & how the last update statistics were run, for medium or high mode only.
select distinct tabname, b.constructed, b.mode
from systables a, sysdistrib b
where a.tabid=b.tabid
order by 1
or can be generated through:
dbschema -d <database> -hd <tabname>
Regards,
Shriyan
