How to get only the first row from a ResultSet

Question

How do I get only the first row from a ResultSet? I know how to iterate through the entire set, but how do I get just the first row?

Answer 1

Instead of iterating over the result set, just check if there exists an entry an read it:

ResultSet r = ...;
if(r.next()) {
  String s = r.getString(1);
  ...
}
