用户id有则更新,无则添加 使用replace into (代替 insert into)

app登录成功后,调用后台,更新channel_id

public function set_pushchannel($device,$channelid,$iv='' )

$sql = "replace into t_push(`push_account_id`,`push_type`,`push_channel_id`)value('".$account_id."','".$device."','".$channelid."')";
$idd = $model->execute($sql);
