“空”列是否创建墓碑？

Question

让我们说我有一个简单的表格：

@Override
public void run() {
    try {
        HttpPost httppost = new HttpPost("MY_URL");
        HttpClient httpclient = new DefaultHttpClient();

        jsonArray = getJSONArray();

        nameValuePairs.add(new BasicNameValuePair("msg", String.valueOf(jsonArray)));

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse httpresponse = httpclient.execute(httppost);
        Thread.sleep(myService.getIntervalCoordinates() * 1000);
    } catch (Exception e) {

    }

用户名列的 new 行的插入值是否为 null 会创建一个逻辑删除吗？
