Can there be constraints with the same name in a DB?

Question

This is a follow-on question from the one I asked here.

Can constraints in a DB have the same name?

Say I have:

CREATE TABLE Employer
(
    E         


        

Answer 1

Does it depend on the DBMS (I'm on SQL Server 2005)?

Yes, apparently it does depend on the DBMS.

Other answers say it's not permitted, but I have a MS SQL CE ("Compact Edition") database in which I accidentally successfully created two FK contraints, in two tables, with the same contraint name.
