Re: virtual relvar with new type
Ok, I have not read that it was not possible, but it seemed a bit peculiar.

Re: virtual relvar with new type
it works, given of course also the foreign key constraints:
CONSTRAINT LP_L_KEY LP {L#} <= L {L#};
CONSTRAINT LP_P_KEY LP {Pt} <= P {Pt};
CONSTRAINT LP_L_KEY LP {L#} <= L {L#};
CONSTRAINT LP_P_KEY LP {Pt} <= P {Pt};

virtual relvar with new type
Hi, I am not sure whether this is a feature or not, but given the following (same as previous bug-posts): TYPE Pt POSSREP {X RATIONAL, Y RATIONAL}; TYPE L# POSSREP {L# CHAR}; TYPE LINESEG POSSREP { LINESEG RELATION {Pt Pt}}; VAR P BASE RELATION {Pt Pt} KEY {Pt}; VAR L BASE RELATION {L# L#} KEY {L#};...

possible rename problem
Hi, I am not sure whether this is a bug or a feature, but maybe you can check this on your machine: Given the following: TYPE Pt POSSREP {X RATIONAL, Y RATIONAL}; TYPE L# POSSREP {L# CHAR}; VAR P BASE RELATION {Pt Pt} KEY {Pt}; P := RELATION { TUPLE {Pt Pt(0.0,0.0)}, TUPLE {Pt Pt(0.0,1.0)}, TUPLE {P...

another group bug
Hi, Is it possible to do multiple groupings on different attributes of a relation? It seems it should be possible but when I try it with the following; / ------------------------------------ type definitions ------------------------------------------ TYPE Pt POSSREP {X RATIONAL, Y RATIONAL}; TYPE L#...

small dbbrowser bug
Hi I think i found a bug in the enhanced mode of the DBbrowser if you have the following: TYPE POINT POSSREP {X RATIONAL, Y RATIONAL}; VAR P BASE RELATION {POINT POINT} KEY {POINT}; P := RELATION { TUPLE { POINT POINT(0.0,0.0)}, TUPLE { POINT POINT(0.0,1.0)}, TUPLE { POINT POINT(1.0,0.0)}, TUPLE { P...
