Thank you for your answer. But in general I would like to know how to get the query exexution time without printing the results. It's for performance comparaison. I want to evaluate MonetDB for my research and i'm working with large tables.

Please any idea??

Hello dear MontDB users,

I have a question please, I just need to get the query execution time without showing the results of the query (for performance comparaison) . Something which corresponds to the "traceonly" in Oracle. that will be greate if I can see the query plan but for the moment the most important for me is to get the query execution time.

for example: I want to know the query exection time of this query (select * from source where a>10) knowing that I have more than one

This is not the ind of query you fire when you expect a large outcome. Better use SELECT COUNT(*)....

hundred million records which correspond to this predicate.

Thank in advace for your appreciated help.

Baraa
