I am trying to add a serial number in my table. Here is my method:

public void reArrangeTrID(){
String parti = name.getText().toUpperCase();    
long trid = 1;

try{
String query="SELECT LONGDATE, TRID FROM PARTIACCOUNT WHERE PARTY= '"+parti+"' ORDER BY LONGDATE ASC ";
conn = new connection().db();
stmtt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
rs = stmtt.executeQuery(query);
while(rs.next()) {
    long tr = rs.getLong("TRID");
    rs.updateLong("TRID", trid);
    rs.updateRow();
    trid++;
    jLabel9.setText("Arranging transactions... Please wait.");
}
 }

catch (SQLException ex) {
JOptionPane.showMessageDialog(null, "Unknown Error!! Data cannot be displayed!"+ex);
}
finally{try{stmtt.close(); rs.close(); conn.close(); }catch(SQLException ex){}}
}

Why this method gives me an error that updateLong not allowed because ResultSet is not an updatable ResultSet, while my resultset is already set to updatable. I am using derby database.

As per javadoc

static final int TYPE_SCROLL_SENSITIVE

The constant indicating the type for a ResultSet object that is scrollable and generally sensitive to changes to the data that underlies the ResultSet.

What you are looking for might be:

static final int TYPE_SCROLL_INSENSITIVE

The constant indicating the type for a ResultSet object that is scrollable but generally not sensitive to changes to the data that underlies the ResultSet.
