Hi Uwe

==> Quick, dirty and most certainly unsupported workaround:

alter table stats$sql_plan add (timestamp date);

My advice is to make what you propose less dirty... i.e.:

ALTER TABLE perfstat.stats$sql_plan ADD timestamp INVISIBLE AS (cast(NULL AS 
DATE))

I don't see how adding such an invisible virtual column could cause a problem.
