Just a clarification...so it's the case that the column parameter in v.dissolve must always be of type integer, and *only* integer?

Well... I suspected it had to do with the field type of the column "CODE_00". Indeed... the column was "TEXT". After Daniels (Victoria) indications for a similar problem a change to "integer" (using sqlitebrowser) solved the problem. I suggest a clarification about that in the man page of v.dissolved. Greets... P.S.
