Hi Jeff,
Thank you.
I've asked them to send output with statistics time but haven't received an answer yet.
The query is just an ordinary:
select * from table
or
select an aggreagte finction(col1) from table_name
col1 is not indexed
The aim is to have a table scan.
In all cases apl/dol relations are almost the same.
I'll aske them to send the output from the script you've added here.
Annie
