PLS-00521: ORDER methods must be declared with 1 (one) parameter in addition to (optional) SELF.

PLS-00521: ORDER methods must be declared with 1 (one) parameter in addition to (optional) SELF.
Cause: An order member function was declared without the user-specified parameter. Order member functions have two parameters, one is the default SELF parameter which is added by the compiler. the second parameter is added by the user and must declare an order method which must be the same type as the containing object type.
Action: Check and correct the way the parameter is specified.

PLS-00521：除了（可选）SELF之外，还必须使用1（一）参数声明ORDER方法。,
.原因：订单成员函数声明没有用户指定的参数。订单成员函数有两个参数，一个是编译器添加的默认SELF参数。第二个参数由用户添加，并且必须声明一个必须与包含对象类型相同类型的订单方法。,
.操作：检查并更正指定参数的方式。,
