问题描述
您好，为什么我会收到此错误?基本上我可以从以下三行中得到它:
Hello not sure why Im getting this error.Basically I get it in these three lines:
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 ;
推荐答案
p_temp_foo是IN参数.本质上，它们是只读的.您可以将其定义为IN OUT参数或OUT参数.
p_temp_foo is an IN parameter. By nature, these are read only. You could define it as an IN OUT parameter, or an OUT parameter.
