[Monetdb-developers] GDK::BAT_select_ problem
Hi, I am doing some developments in GDK. More concretely, I want to modify the behavior of a SQL select statement. I print some messages in BAT_select_ as I think that most of SQL selects would be compiled into plusieur BATselects. Is that right? I used mserver --dbinit 'include sql;' to start, and saw some messages coming out (BAT_select_ is also used for authentication). However, after I logged in by using mclient -l sql, no matter what kind of SELECT I performed, there was just no message. Was BAT_select_ called after all in this case? Thank you very much for your responses. Regards, Richard _________________________________________________________________ MSN 表情魔法书，改变你的对话时代！ http://im.live.cn/emoticons/

The easiest way to get output (debug statements) from gdk is to run using mclient with -fraw and use --algo and --performance on the mserver5. Niels
Thank you very much for your responses.
