sql - Retrieve Next Purchase Order Due and Price from that Order -

-

मेरे पास ऐसा खरीद ऑर्डर तालिका है: 

  + ------ --------- + ------------ + --------- + ---------- + ------ - + | खरीदऑर्डर | देय तिथि | उत्पाद | मात्रा | मूल्य | + --------------- + ------------ + --------- + ---------- + ------- + | PO1 | 04/12/2014 | ए | 20 | 19 | | पीओ 2 | 20/11/2014 | बी | 16 | 22 | | पीओ 3 | 07/11/2014 | ए | 14 | 32 | | PO4 | 09/12/2014 | बी | 7 | 86 | + --------------- + ------------ + --------- + ---------- + ------- +

मैं प्रत्येक उत्पाद के लिए मात्रा का योग करने के लिए एक क्वेरी चाहूंगा, अगले नियत दिनांक को प्रदर्शित करता हूं, और उस खरीद आदेश से मूल्य प्रदर्शित करता हूं अगले कारण।

वांछित आउटपुट होगा: 

  + --------- + ------------- - + -------------- + ------------------ + | उत्पाद | कुल मुक्ति | NextDueDate | NextDueDatePrice | + --------- + --------------- + -------------- + -------- ---------- + | ए | 34 | 07/11/2014 | 32 | | बी | 23 | 20/11/2014 | 22 | + --------- + --------------- + -------------- + -------- ---------- +

बिट मैं नहीं जानता कि कैसे करना है (सबसे कारगर तरीके से) NextDueDatePrice प्राप्त करना है!

< P> मैंने एक SQLFiddle सेटअप किया है जो कि सभी करता है लेकिन वह कॉलम यदि यह मदद करता है:

किसी भी मदद के लिए पहले से बहुत धन्यवाद!

उप-कुंडली पद्धति का उपयोग:

एमएस एसक्यूएल सर्वर 2008 स्कीमा सेटअप :

<प्री> बनाओ टैब खरीद ऑर्डर (खरीद ऑर्डर वर्चार (255), डेट डेट, टाइम टाइम, उत्पाद varchar (255), मात्रा इंट, प्राइस इंट,); खरीद ऑर्डर के मूल्यों में INSERT ('पीओ 1', '2014-12-04', 'ए', 20, 1 9); खरीद ऑर्डर के मूल्यों में INSERT ('पीओ 2', '2014-11-20', 'बी', 16,22); खरीदऑर्डर्स वैल्यू में INSERT ('पीओ 3', '2014-11-07', 'ए', 14,32); खरीदऑर्डर्स वैल्यू में INSERT ('पीओ 4', '2014-12-09', 'बी', 7, 86);

प्रश्न 1 : 

  SELECT उत्पाद, SUM (मात्रा) के रूप में कुल मूल्य, MIN (DueDate) AS NextDue, (Select

से खरीदें PurchaseOrders p2 से मूल्य जहां p2.Product = p1.Product और p2.DueDate = MIN (p1.DueDate)) :

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 ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

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. ...
