1. using C++ to define new functions

   David Gross <david.gross@lri.fr> — 1998-07-17T08:59:17Z

   Hello,
   
   	Sorry to disturb the hacker list for a question that seems not so hard.
   But I got no answers elsewhere...
       Is is definitively impossible to use C++ to define new SQL functions or operators
   in SQL ? (I need this in order to use a big geometric library, to produce e.g. polygon
   intersections, or harder).
   
   	       I manage to add C functions, with a
   
   	       create function ... returns .. as language 'c';
   
    but the linking style of c++ is rather different.
   Do you have an idea ?
       
   Thanks,

   How about using extern "C" {...} ?
