How to retrieve partial data in SQL Server ?

I am trying to display 4 columns of a particular table. The browser

is displaying 50 records per page. 'Next' and 'Previous' buttons are

there for navigating through all the records. It may have even 1

million or more records. The table may have n number of records. I am

not getting any problem if the record size is approximately 50,000.

But for large number of records say, 1 lac or more, the browser is

taking too much time...roughly, for 1 lac record it is taking 35

seconds and for 2.5 lac record it is taking 4 minutes...as the no of

records fetched increases...page loading time also increases

exponentially. So, my aim is to collect partial data from the table

and display it. In oracle I can manage it using rownum and minus

clause, efficiently. But in SQL Server I am not able to handle it,

using those technique. My application runs both on Oracle and SQL

Server. Can anybody help me?

For more clarity :::: I want to collect 1 to 50 records from the

table. next time I want to collect records from 51th. position to

100th. position. And then from 101th. position to 15oth. and so on.
Of course in SQL Server.

I am writing my code in JSP.

Thanks -

Here are some notes on prior pagination discussions. See if any of these ideas fit your situation. Let us know if you think of better ones!
