entity framework - Deferred Execution -


मैं जानना चाहूंगा कि आलसी लोड हो रहा है == स्थगित निष्पादन?

नहीं

"आलसी लोडिंग" आमतौर पर यह इंगित करने के लिए प्रयोग किया जाता है कि यदि आपके पास एक ऐसी संस्था का उदाहरण है जो किसी अन्य इकाई को संदर्भित करता है, तो कोड में प्रॉपर्टी को हटाना एक डेटाबेस क्वेरी को अमल में लाना होगा यदि वह पहले से ही लोड नहीं हुआ है, तो वह अन्य इकाई।

उदाहरण: 

  var foo = Context.Foos.First (); Var bar = foo.Bar; // आलसी लोडिंग के साथ, यह फ़ू के लिए डीबी क्वेरी का कारण बनता है।

"डिफर्ड निष्पादन" का आम तौर पर मतलब है कि जब तक कोई IQueryable चलती नहीं है तब तक कोई भी डेटाबेस क्वेरी जारी नहीं की जाएगी।

उदाहरण

<पूर्व> var foos = context.Foos.Where (f = & gt; f.Id == आईडी); // no डीबी क्वेरी; स्थगित हुए var foo = foos.First (); // अब एक क्वेरी जारी की जाती है। Var गिनती = foos.Count (); // एक अन्य क्वेरी जारी की गई है

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net - getting a value of selected radiobutton in LoadViewState -

Can I get the value of a selected radio button in the LoadViewState event of WebControl and how? All components are generated in codebehind, so I have those controls: Radiobutton list RLL; LISTIME leon; List liTwo; At this time I was stuck on that the overloaded loadviolet is not being implemented protected override zero load vivestat (object o) {action = Rbl.SelectedValue; Verb 2 = rll Selected item. value; Base.LoadViewState (O); } You also need to override the SaveViewState method. Radio button AFAIK has problems in saving their selected state.
