Update of /cvsroot/monetdb/pathfinder/compiler/algebra
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv31404/compiler/algebra
Modified Files:
planner.c
Log Message:
The error operator now reaches all the way to the mil level.
* planner.c: added code for actually creating the physical plan with the error
op.
* milgen.brg: for the time being only prints a standar error, next commit will
print the correct string
* logical.h: added a semantic content for the error operator
Index: planner.c
