Hi Fabian,Thanks for looking into this. The reason why i want this is that I can't figure out why my udf function does not work. I added a MAL function to the udf.c and related files, it works when i used it in mal client, but can't make it work in sql after creating a sql function. I checked the udf.reverse example, looks like it need only a SQL function for the scalar version of reverse, and the batudf.reverse will be used automatically if i "select reverse(colname) from table". Anyway, i tried different combination, my scalar version udf function works, but BAT version don't work, thinking that sql_debug might provide some info for me before i jump into gdb. As to setting this parameter, i know i can use mserver5 --config=filename, or just mserver5 --set sql_debug, but don't know how to let monetdbd to use a configuration file. thanks for your help!George

Hi, I want to set?sql_debug=16384 for mserver5, where can i set this value? I can't find any documentation on where's the monetdb configuration file.

Why would you want that?

If you're sure you want so, it should be clear to you how to do that as well. This is absolutely not a supported mode of operation.

Fabian
