Hi,
You can add a new table constraint (to check one or more columns) by
right-clicking the Constraints node under the table and selecting New
Object -> New Check Constraint. I don't think any of us ever saw much
value in allowing constraints directly on individual columns as well -
it would just over-complicate the GUI for no real gain.
