Hello I would like to implement a new data type next to char, number, varchar... for example a special "Money" type, but I don't want to use extensions and the Create type command. I want to implement it directly inside source code, because I want to implement my new type at lower level, in order to perform some more sophisticated functions after. Just as an example, help the optimizer in its decisions. How should I proceed ? Is it an easy task ?
Thanks Mohand
