    StringBuffer sql = new !StringBuffer():
    List params = new ArrayList();
　　sql.append(" update T MY_TEST");sql.append(" set FName = ?,                 
　　FDate =? where FID=?"):
 　 params.add(strName):
　　Date date = new Date();
   long time = date.getTime();
   params.add(ncw Timestamp(time));
   params.add(id);
   com.kingdee.eas.util.app.DbUtil.execute(ctx, sql.toString(),params.toArray();
