    I would like to know the syntax for putting a table constraint as follows:

    Create Table tmp(id number, name varchar2(13));

    How do I put a constraint if id =100 then name must be 'Peter' . I dont want to make use of triggers.

    Thanks

    AFAIK you cannot do that, a check constraint on 1 column cannot reference another one, and I don't see how you could use another type of constraint to do that ...
