Answer 1

Here is my code
create or replace procedure (valid_no IN number) as
Begin
select valid_no from table2 where valid_no = ?(How to
give the input parameter here)
Update ----
end;
My valid_no comes from diferent work flows.so i need
it to take as dynamicFirstly, don't name your parameters the same as your table columns otherwise it'll confuse things.
i.e. it's more readable like:
create or replace procedure (p_valid_no IN number) as
  v_valid_no number;
Begin
  select valid_no
  into   v_valid_no
  from   table2
  where  valid_no = p_valid_no;
  Update ----
end;Although you would be more likely to select something other than valid_no from the query as you already know that from your input parameter.
Now if you have multiple input values to pass in, that's a different matter.
