Is it possible to select the data using indexes without using select statement...
No, you can not, you have to use it anyway. You can use stored procedure and call them from asp.net but stored procedure would have select statement to get data from tables.

I create an one webpage in asp.net all the time i am facing the following pbm how to rectify it..
if(ds.Tables[0].Rows.Count > 0)
Maybe you need to check that ds.Tables[0] exists first
If you are constantly checking on your pages to see if that dataset has a table with rows, I would think you would want to make some helper class to check that your dataset is not null, and that whatever tables have actual rows. Also you might want to think about moving these to typed datasets.

how to reverse records in pl/sql
Use an ORDER BY clause with either ASCENDING or DESCENDING when selecting your records.
If this isn't what you want, you need to learn how to ask questions, as this is rather vague and open to interpretation.

asp.net mvc module wise approach or different controller and repository for each table approach is better?
Could you elaborate on your question? I think I understand... I like creating a repository for each table in a LINQ-to-SQL or entities model, for instance. I think that helps group together related logic.
HTH.
