小小宇 的农场后台删除错误！

点删除后提示这个错误

MySQL Error
Message: MySQL Query Error
SQL: DELETE FROM uchome_happyfarm_mclog WHERE uid=17
Error: Table '28wol.uchome_happyfarm_mclog' doesn't exist
Errno.: 1146


实际刷新发现数据已经被删除

代码为：

$_SGLOBAL['db']->query("DELETE FROM ".tname('happyfarm_config')." WHERE uid=".$id);
  $_SGLOBAL['db']->query("DELETE FROM ".tname('happyfarm_nc')." WHERE uid=".$id);
  $_SGLOBAL['db']->query("DELETE FROM ".tname('happyfarm_mc')." WHERE uid=".$id);
  $_SGLOBAL['db']->query("DELETE FROM ".tname('happyfarm_mclog')." WHERE uid=".$id);
  showmessage('删除用户的农牧场成功', 'admincp.php?ac=farm');

实在是找不出那错了  请高手指点！
