How to create hidden Field in Storage Engine?

[xiao feng]

hi, 
   I have asked this question some moths.

   How to create hidden fields  in Storage Engine?
   when use create a table, I can add a hidden field to it, it can't show when client show
tables, but it can be used for select or insert or delete?
  table1:
         field1, field2.
 SQL:
       select * from table1 where hidden_field = "hidden_data".
       I want to use a hidden_field as "myrowid", or some thing else.

Thanks!
