Is it possible to apply a constraint or equivalent to a table that prevents a record being inserted when the record to be inserted already exists but the values are swapped around?

For example, if a table had two columns: FirstName and SecondName having a record FirstName = ‘John’ and SecondName = ‘Smith’ – then when another record having FirstName =’ Smith’ and SecondName =’ John’ was about to be inserted SQL would reject it.

Good luck!
