Update of /cvsroot/monetdb/pathfinder/compiler/mil
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv17783/compiler/mil
Modified Files:
milgen.brg
Log Message:
* Algebra and MIL implementation of the XQuery update functions:
upd:delete
upd:insertAfter
upd:insertBefore
upd:insertIntoAsFirst
upd:insertIntoAsLast
upd:rename
upd:replaceElementContent
upd:replaceNode
upd:replaceValue
There is some things that must be still done in the algebra level, e.g.,
reverse the order of the sequence in the insertBefore/insertIntoASFirst
functions. Also the mil implementation of the serialize operator for
updates is not done yet. So basically updates wont work yet in the
algebra backend, but we are getting closer.
