However, you can enforce constraints on views through constraints on base tables. You can specify only unique, primary key, and foreign key constraints on views, and they are supported only in DISABLE NOVALIDATE mode. You cannot define view constraints on attributes of an object column. See Also:A unique constraint is a type of constraint in SQL databases. It defines a field or set of fields where the combination must be unique in a table. So, if you create a unique constraint on one column, all of the values in that column must be unique.
