php - My system is fetching data from a wrong table -

-

Instead of receiving data from the DOC_PROGRESS table, it continues to retrieve data from

table I need data from both tables but I think I am doing it wrong. My query is down, by the way. Please help me 
  (from the selection "dd as JOIN doc_progress AS dp ON dd.p_id = dp.p_id WHERE (dd.p_id = '". $ _ Session [' currentUser ']. "') And (dp.progress =' ​​read ')");   
  & lt ;? Php $ select1 = "doc_progress" as the ASD DP JOIN DOC DD ON dd.p_id = dp.p_id WHERE (dd.p_id = ''. $ _ Session ['current user']. "") And (dp .progress = 'unread'); $ Sql ​​= mysql_query ($ select1) or die (mysql_error ()); while ($ row2 = mysql_fetch_array ($ sql)) {? & Gt; & lt; tr square = " Strange Grade X ">   echo $ row2 ['date_created']? & Gt; & lt; / td> & lt; td & gt; & lt; a Href = "" & gt; & lt ;? php echo "& lt; B & gt; ". $ Line2 [[document_title ']." & Lt; / P & gt; ";? & Gt; & lt; / a & gt; & lt; / TD & gt; & lt; TD & gt; & lt ;? php echo $ row2 ['status']? & Gt ;  & lt; td & gt; & lt ;? php echo $ row2 ['progress'];? & Gt; & lt; / td> & lt; td & gt; & lt;    
  
 Use it  
  ("SELECT DD. *, DP. * DD inner join doc-progress DP on document. DD.p_id = DP.p_id where DD.p_id = '". $ _ Session [' Current User '].' 'And DP, Progress =' ​​Read '");

python - Receiving "KeyError" after decoding json result from url -

-
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...

C++ Array Type Not Assignable in Copy Constructor -

-
I have a simple class that represents the triangle, which consists of three arrays square triangle {public: double x [3]; Double y [3]; Unsigned four colors [3]; }; I want to create objects in this square on the heap, then pass on those functions which will use the value from the array. Since I am in these items, I need to make a deep copy to make a copy. Triangle (const triangle and obj) {X = new double [3]; Y = new double [3]; Color = new unsigned char [3]; For (int i = 0; i I keep the following error: "Error: array type 'double [3]' is not assignable for each of the three arrays. I am taking the same view as discussion, and I do not know why I am unable to create a new array. The answer is also the same approach. Does anyone have any insights? Looks like I'm really stupid. I'm taking the same approach as discussed in this video. In the video, you can see that he started the array Read on the member-preliminary list and how it is dif...
