Using a Foreign Table to Constrain Values
A foreign table can also be used to constrain values. To use a foreign table in this way, specify a value and a display column that are the same column. In addition, set the Constrained option in the appropriate inspector to Yes.
This ensures that only the values contained in the foreign table display (value) column can be entered by the user.
