Thank you for quick reply. So, you mean the '-f none' option is not working?? and, when testing monetDB performance with tpc-h like benchmark, the performance is tested using 'cat file.sql |mclient -lsql -t -f raw |grep Timer' ?? Thanks so much. Maria Re: [MonetDB-users] monetdb output mode -f From: Martin Kersten <Martin.Kersten@cw...> - 2009-03-25 19:58 Maria wrote:
Hi, I would like to run query with out printing output in order to monitor its performance. I tried to use '-f none' in command-line, but it didn't work for monetdb5. (I am not using xquery here) The way to avoid the timing in output rendering then you might consider replacing your queries by count(*) queries. In all other cases, the data is sent from server to mclient for rendering. If you use the mode 'raw' this amounts to a plain dump without further rendering concerns. The following might be what you want:
cat file.sql |mclient -lsql -t -f raw |grep Timer
./mclient -lsql -uxman -ddemo -t -f none 1.sql
===> then, it prints all the results on the screen and display time.
I want it only display time, not the query results. I also tried to redirect using /dev/null. In this case, it didn't display time.
Isn't the '-f none' working in monetdb5?? If so, how can I measure the query time ?
Thanks in advance. Maria.
