I aplogize for bothering you with what might be a simple issue for you, but I am new to monetDB and I have to solve some complex problems for which I cannot find a solution by myself. I've read about MAL in the M5 reference manual. I recognized, the normal way to execute commands is via MAPI and JDBC and stuff based on MAPI. This will be parsed into MAL, optimized and executed. Is there a way to write MAL code and give it as input to the server directly??

Another question: Is it possible to explicitely invoke execution of a query in multiple threads via MAPI or other means?
