| Are you absolutely sure you need that feature? It's pretty dangerous and not recommended.If you absolutely insist (and don't say you weren't warned) you'll find the syntax in Books Online under "ALTER TABLE...ADD CONSTRAINT". |

| you will need to drop the foreign constraint and again create it. |
