I would like to compare values ​​between 2 separate tables and only return the difference but IM will come with a query Is struggling for.

I have an employee tab 1 and employee tab 2. I am comparing data between God and testing.

Employee 1 

  order1 1 Reg Reg2 regular 2 temporary floating 3 Reg Regular 4 new new rent 5 del end
< P> employee2 

  id2 cd2 desc2 1 regulate regular 2 temporary temporary -456 3 regular reg-123 4 new new rent 5 del end

My result should be set (i < <

  Id cd1 desc1 cd2 desc2 1 reg regular reg regular-123 2 temp temporary temporary temporary -456   
 i tried this approach  
  select EMPL_ID, S D1, 1, CD2, 2 to Ampl 1, Employ 2 WHERE EMPL_ID1 = EMPL_ID2 and CD1 = CD2 and desc1 & lt;> desc2  
 
 but give it duplicate results Thank you for your help!

Depending on your data, you may see id < / Code>, cd1 : 

  do not select empl1.EMPL_ID, cd1, desc1, cd2, desc2, empl1 empl2 at empl1.EMPL_ID = empl2.EMPL_ID and empl1 CD1 = Empl2.cd2 and empl1.desc1 & lt; & Gt; Empl2.desc2;

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()?

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
