Imposing Functional Dependencies

Hi,


I have a table   myTable(A,B,C,D). I know that for a given C value, the
value of D is fixed. Thus C functionally determines D. I don't want to
normalise the table. I only want to enforce this constraint so that nobody
inserts rows that have different values for the same value of C. How do I
set the constarint? I am looking for the Oracle DDL statement in particular.



Thanks.
