Statement lstmt = null;

try {lstmt = Connectdb ();

rs = lstmt.executequery (SQL);

System.out.println ("executequery:" + sql);

The catch (SQLException ex) {return (null);}

Return RS;

}

public string executeupdate (String sql)

{

Statement lstmt = null;

try {

lstmt = Connectdb ();

Lstmt.executeupdate (SQL);

System.out.println ("executeupdate:" + sql);
