Anchored types, i.e. those specified using either ``++%TYPE++`` or ``++%ROWTYPE++``, cannot be constrained. Trying to do so results in the exception ``++PLS-00573: cannot constrain scale, precision, or range of an anchored type being raised.++``


== Noncompliant Code Example

----
DECLARE
  foo DUAL.DUMMY%TYPE(42); -- Non-Compliant - raises PLS-00573
BEGIN
  NULL;
END;
/
----


== Compliant Solution

----
DECLARE
  foo DUAL.DUMMY%TYPE; -- Compliant
BEGIN
  NULL;
END;
/
----
