The following request is not valid because the constraint named dup_constr_name already exists in table_1. You cannot add it to the table.

    ALTER TABLE table_1
      ADD CONSTRAINT dup_constr_name
      FOREIGN KEY (column_3) REFERENCES table_2;

The system returns the following message:

Constraint with the same name 'dup_constr_name' already exists in table.
