Opening an updatable ResultSet

  


import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.Statement;

public class PrintResultSet {
  public static void main(String args[]) throws Exception {
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    Connection con = DriverManager.getConnection("jdbc:odbc: Contacts");
    Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
        ResultSet.CONCUR_UPDATABLE);
    ResultSet rs = stmt.executeQuery("SELECT Name,Description,Qty,Cost FROM Stock");
    ResultSetMetaData md = rs.getMetaData();

    if (rs.getConcurrency() == ResultSet.CONCUR_UPDATABLE)
      System.out.println("UPDATABLE");
    else
      System.out.println("READ_ONLY");

    int nColumns = md.getColumnCount();
    for (int i = 1; i <= nColumns; i++) {
      System.out.print(md.getColumnLabel(i) + ((i == nColumns) ? "\n" : "\t"));
    }
    while (rs.next()) {
      rs.updateString("Street", "123 Main");
      rs.updateRow();
      for (int i = 1; i <= nColumns; i++) {
        System.out.print(rs.getString(i) + ((i == nColumns) ? "\n" : "\t"));
      }
    }
  }
