mysql - Top 3 results from each player and sort by total -

-

I need to come up with results that show the sum of the top 3 results from each player and to sort it Yog

Example Table: 

  David = 12 Mike = 17 John = 20 Bill = 20 David = 12 Mike = 16 John = 18 Bill = 20 David = 11 Mike = 15 John = 16 David = 10 Mike = 14 John = 16 David = 10 John = 15   
 The results need to be shown as follows:  
  John = 54 Mike = 50bill = 40 David = 35   
 I have to Place Ranking for all the events from the Le (simple):  
  SELECT playerName, SUM (`EventPoints`) DESC   
 I have PHP code Thinking about the following:  <`Ol> 
  •  Create a table named top3Events  
  •  Truecover Top 3 Avents at Startup  
  •  On the table event, the above query Read through the results  
  •  Use the counter and reset the new player name to each  
  •  INSERT in the top 3 events when cou nter & lt; = 3   
     Run this query:  
      SELECT playerName, SUM (`eventPoints`) Order by 'playname` from' Top 3 Events Group ' (`Event Points') DESC   
     To ensure that this is the correct way to go with it

    -
    I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

    .net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

    -
    "itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
