Update of /cvsroot/monetdb/pathfinder/compiler/include
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv15930/compiler/include
Modified Files:
logical.h
Log Message:
-- Changed the semantic content of the la_ref_tbl operator.
-- In the semantic content of the la_ref_tbl operator we now store the
*positions* (w.r.t. the schema) of key attributes instead of their names, so
that renamings of attribute names (e.g. by some plan optimization phases) don't
have to be done additionally on this key attribute infos.
