Feauture not supported Exception thrown from RowSet.

Question

When running
import java.sql.SQLException;
import javax.sql.RowSet;
import com.sun.rowset.JdbcRowSetImpl;
public class TestRowSet {
     public TestRowSet() {
          try {
               Class.forName("com.mysql.jdbc.Driver");
               RowSet rowset = new JdbcRowSetImpl();
               rowset.setUrl("jdbc:mysql://localhost/test");
               rowset.setUsername("root");
               rowset.setPassword("root");
               rowset.setCommand("select * from Account");
               rowset.execute();
               rowset.next();
               rowset.setString("password", "password");
               rowset.updateRow();
          }catch(Exception ex) {
               ex.printStackTrace();
     public static void main(String[] args) {
          new TestRowSet();
}I get
java.sql.SQLFeatureNotSupportedException: Feature not supported
     at com.sun.rowset.JdbcRowSetImpl.setString(Unknown Source)
     at TestRowSet.<init>(TestRowSet.java:20)
     at TestRowSet.main(TestRowSet.java:29)I'm using the latest driver. So am i to take from this that RowSet is not fully implemented in the driver and I should just use ResultSet, or is it something else?

Answer 1

If there is another documented way of using row sets I haven't found it.
Not that I have the slightest idea of what they are for, except CachedRowSet. Why you would want to de-transactionalize an update and fetch all the rows and then update them yourself when SQL can almost certainly express the whole thing without the round trips and latency and extra lock time and extra Java code is a mystery to me. I was once required to do all that after I had already written a single SQL statement that would do the entire job. I don't work there any more ;-)
