Update of /cvsroot/monetdb/pathfinder/compiler/algebra/map
In directory
sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv20201/compiler/algebra/map
Modified Files:
intro_thetajoin.c map_ori_names.c map_unq_names.c
Log Message:
Basic Algebra implementation for the fn:error functions (32 files edited).
Introduced a new operator on the logical level, namely la_error.
Operator la_error takes a BAT of strings as parameter (containing the error
message) and carry it all the way until the MIL level where the conditions are
checked and the mil if-statement is printed.
Disclaimer:
Most likely the switch-case clauses on the prop/ and opt/ directories
are not always treated correctly for the la_error operator, but a man has
to start from somewhere.
