title: what is the select top equivalent in oracle10g
body: <p>I am currently working on an application which queries database- Oracle 10g. 
  Is there any thing equivalent in Oracle to get the same as we use Top(x) in SQL Server? I want Data in order it is added in table.
  Any help would be appreciated.</p>
  
  <p>Please note that I don't want 5 highest values. I want 5 top values. It is about ordinal position the physical order in which rows added to the table. No any sorting even by index.</p>
