Restrictions with the Multiple-Column Constraint Format

When you use the multiple-column constraint format, you cannot define any default values for columns. In addition, you cannot establish a referential relationship between two columns of the same table.

To define a default value for a column, or to establish a referential relationship between two columns of the same table, refer to Single-Column Constraint Format or to Referential Relationships Within a Table respectively.
