At runtime, you can use our Low Level ADO.API
to execute SQL script that specifies a table column as unique.
However it is not currently possible to specify non Primary Key property as unique via your model and then push the constraint to the database. We do however have a request
for such feature at our Feedback Portal. We would like to invite you to vote for it as doing so will help us to prioritize its eventual implementation.
You can also consider whether a custom validation attribute
would be and applicable approach for your situation.
I hope this helps. If you have additional questions or need help, feel free to post at our forums again.
