Update of /cvsroot/monetdb/pathfinder/compiler/semantics
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv11958/semantics
Modified Files:
xquery_fo.c
Log Message:
- implement product aggregate as pf support function. This method is not in the
XQuery standard but is very usefull for us. Only implement the double version
for this moment but to support all possible signatures analog to the "sum"
aggregate we only have to copy-and-mopdify this signature list (9 sigs):
pf:product (double*) as double
