What is difference between TYPE_SCROLL_INSENSITIVE and TYPE_SCROLL_SENSITIVE ResultSet type in java? TYPE_SCROLL_INSENSITIVE is not sensitive to the changes made to the data that underlies the ResultSet. TYPE_SCROLL_SENSITIVE is sensitive to the changes made to the data that underlies the ResultSet.

Can we use ResultSet after closing connection?

What is ResultSet interface?
