Oracle PLS-00363:表达式''不能用作赋值目标

Question

你好,不知道为什么我得到这个错误.基本上我在这三行中得到它:

PLS-00363: expression 'p_temp_foo.editable.modified_by' cannot be used as an assignment target
PLS-00363: expression 'p_temp_foo.editable.date' cannot be used as an assignment target
PLS-00363: expression 'p_temp_foo.editable.modified_by' cannot be used as an assignment target

程序:

 PROCEDURE run_temp_procedure (p_temp_foo IN part_bean, p_member_number IN NUMBER)
 IS
 t_temp_foo part_bean;
  now   DATE;
  BEGIN
  now := SYSDATE;

             p_temp_foo.editable:= t_temp_foo.editable;
        p_temp_foo.editable.date := SYSDATE;
        p_temp_foo.editable.modified_by := p_member_number;


  END run_temp_procedure ;

Answer 1

p_temp_foo是一个IN参数.从本质上讲,这些是只读的.您可以将其定义为IN OUT参数或OUT参数.
