Your post probably belongs on the JDBC forums. I will move it there

Scrollable will allow you to traverse the fetched rows in any diection (backward and forward) using the next() and previous() methods.

The non scrollable version will throw some exception on using the previous() method.

You can define the type of resultset using the constructor (Not completely sure of this)

Write a sample program to verify that.

I create the resultSet by following but not sure what is the performance of scrollable resultSet on huge data set. So I need perfromance comparison in this regard.

conn.prepareStatement(qry, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
I agree. Here's the link: http://aspose.com/file-tools
