PLS-00588: unqualified instance attribute references allowed only in member methods

PLS-00588: unqualified instance attribute references allowed only in member methods
Cause: An attempt was made to use the name of an object instance attribute in the body of a static method, or in an initialization default value on another attribute. If the instance attribute is not qualified with a particular object instance that supplies a value, the instance attribute can be named only when it is inside a member method.
Action: Qualify the attribute reference with the name of an object value, or change the containing method to a member method rather than a static method.

PLS-00588：只允许在成员方法中使用不合格的实例属性引用,
.原因：尝试在静态方法的正文中使用对象实例属性的名称，或在另一个属性的初始化默认值中使用。如果实例属性不具有提供值的特定对象实例的限定，则只有当属性位于成员方法中时，才能命名实例属性。,
.操作：使用对象值的名称限定属性引用，或将包含方法更改为成员方法而不是静态方法。,
