Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Usage

From source file:JndiDataSource.java

public static void main(String args[]) throws Exception {
    String sp = "com.sun.jndi.fscontext.RefFSContextFactory";
    String file = "file:/e:/JNDI";
    String dataSourceName = "jdbc/myDatabase";

    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, sp);
    env.put(Context.PROVIDER_URL, file);
    ctx = new InitialContext(env);

    bindDataSource(ctx, dataSourceName);

    DataSource ds = null;/*from w  ww.j ava2 s .  co  m*/
    ds = (DataSource) ctx.lookup(dataSourceName);

    Connection conn = ds.getConnection();

    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT Name FROM Employees");

    while (rs.next())
        System.out.println(rs.getString("name"));

    ctx.close();
    rs.close();
    stmt.close();
    conn.close();

    ctx.close();
    conn.close();
}

    ResultSet rs = st.executeQuery("SELECT * FROM survey");

    // Move cursor to the last row
    rs.last();//from w ww.  ja  v  a  2  s  .  com
    // Get data at cursor
    String id = rs.getString("id");
