Question

当我查询：

select * from EventLog as q
where EventTypeId = 3 and q.SomeUserId is not null
order by q.UserId, q.TimeStamp

示例结果是：

 ID USERID SomeUserId EventTypeId  
 36723  1   2333    3   13001009809 NULL    115 2015-01-23 14:56:42.860
 36735  1   2334    3   13001009809 NULL    12  2015-01-23 15:48:14.363
 36747  1   2335    3   13001009809 NULL    33  2015-01-23 21:22:48.007
 36769  1   2338    3   13001009809 NULL    22  2015-01-24 11:55:29.100
 36853  1   2347    3   13001009999 NULL    61  2015-07-06 17:24:33.817
 36863  1   2351    3   13001034120 NULL    25  2015-12-23 11:42:48.463
 36873  1   2352    3   13001034120 NULL    25  2015-12-23 11:46:25.030
 36883  1   2353    3   13001034120 NULL    10  2015-12-23 11:49:09.553
 964    10  826 3   01005000095 NULL    NULL    2013-01-30 15:52:17.653
 973    10  829 3   01009005715 NULL    NULL    2013-01-30 16:20:46.293
 637    12  752 3   35001091797 NULL    NULL    2013-01-15 16:50:54.567
 738    12  767 3   35001091159 NULL    NULL    2013-01-18 10:53:04.143
 1316   12  870 3   35001119598 NULL    NULL    2013-02-07 11:36:28.503
 1377   12  888 3   59002002288 NULL    NULL    2013-02-07 13:24:57.777
 1389   12  892 3   35001104167 NULL    NULL    2013-02-07 14:01:40.920
 1408   12  897 3   20001009805 NULL    NULL    2013-02-07 15:05:08.577

最后一个是时间戳（另一个并不重要）

如何选择结果：

例如每月注册的SomeUserId是：

1月20日// 0 + 20 = 20

2月50 // 20 + 40 = 70

3月35日// 70 + 35 = 105.现在它是100+。所以在那个查询之后必须   从头开始归还所有东西

4月10日// 0 + 10 = 10等

和每个SomeUserId（这里是1,10,12 ......）

它基于100个注册用户（不会有3个月或12个月的事情）。

Answer 1

    please check your path from mHighQualityImageUri because output path is not found, below code is modify please check it, it work and remember camera result is give in Main Activity class because You used Fragment so declare on activity Result in Main Activity (Fragment Activity) class.   
//on Fragment Class
private void takePhoto() {
             /*   mHighQualityImageUri = Util.generateTimeStampPhotoFileUri(getActivity());
                Log.d(UploadPicturesFragment.class.getSimpleName(),
                        "URI: " + mHighQualityImageUri.toString());*/
                imageUri =Uri.fromFile(new File("/sdcard/"));
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                context.startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
            }

    //on Main Activity Class
      @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (requestCode == 1) {
             /*   Log.d(UploadPicturesFragment.class.getSimpleName(),
                        "IMAGE URI NOT NULL: " + (mHighQualityImageUri == null));*/
                try {

                    /*if(imageUri==null){
                        Log.i("Bitmap", "Image URI Null");
                    }else {
                        Log.i("Bitmap","Image URI is not Null");
                    }*/
                    Uri imageUri = Uri.fromFile(new File("/sdcard/"));
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(),imageUri);
    //                        mHighQualityImageUri);
                    if(bitmap !=null)
                    {
                        Log.i("Bitmap", "Bitmap not Null");
                    }else {
                        Log.i("Bitmap","Bitmap is Null");
                    }
                    //  DroomUtil.beginCrop(mHighQualityImageUri, getActivity(), this, true, bitmap.getWidth(),
                    // bitmap.getHeight());
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            super.onActivityResult(requestCode, resultCode, data);
        }

Answer 2

您可以使用CASE表达式。
