Stefan, Thank you again. I would like to use CREATE FUNCTION and have been successful with this create function a (x int, y int) returns int return x*y; yet I try to do more complete versions with begin/end like this (and many similar variations) without success. create function b (x int) returns int begin declare retval int; select someval into retval from mytbl where id=x; return retval; end; I am confused with trying to correctly learn the documentation. I searched src/tests for examples but they are only easy like my first that works. Separately, I try to read as much as possible from the website as you've said and I also read the sourceball which leads me to many things like rank() and row_number() and they seem to be working yet I don't find many of these in the website. (That was my question about Mx.) I am trying to use things I should not? At least I would like to understand create function as I can then try to make a lag ability. Thank you for you're patience.

Hi Paul,
Mx is only used "internally" for MonetDB development; it's not meant for let alone required by users, and hence not distributed with the MonetDB release.
All user-relevant documentation (partly indeed extracted from the Mx-based code base using Mx) should be available online on the MonetDB web site at http://www.monetdb.org/ aka. http://monetdb.cwi.nl/
Stefan
ps: In case you are indeed interested in the documentation of Mx itself, you find it at http://old-www.cwi.nl/themes/ins1/publications/docs/KeScBeBo:UNPUBLISHED:96....
pps: In case you are indeed interested in Mx itself, you find the source in the "buildtools" in the MonetDB CVS repository on SourceForge; cf., https://sourceforge.net/projects/monetdb/develop http://monetdb.cvs.sourceforge.net/viewvc/monetdb/buildtools/Mx/

Can someone tell where the Mx utility is for creating the documentation? I have seen references in sources to this command and searches are trouble with only two letters like mx.
Is this documentation different/more than the nl website?
Thank you. Paul
