Specify a name for the WITH CHECK OPTION constraint. If you omit
    the name, SQL creates a name. However, Oracle Rdb recommends that
    you always name constraints. If you supply a name for the WITH
    CHECK OPTION constraint, the name must be unique in the schema.

    The name for the WITH CHECK OPTION constraint is used by the
    INTEG_FAIL error message when an INSERT or UPDATE statement
    violates the constraint.
