Question

I have used a ResultSet that returns certain number of rows. My code is something like this:

ResultSet res = getData();
if(!res.next())
{
    Sy         


        

Answer 1

You can use res.previous() as follows:

ResulerSet res = getDate();
if(!res.next()) {
    System.out.println("No Data Found.");
} else {
    res.previous();
    while(res.next()) {
      //code to display the data in the table.
    }
}
