php - Mysql_fetch_assoc(): supplied argument is not a valid MySQL result … -


संभव डुप्लिकेट:

मैं जो कुछ सोच सकता था, मैंने कोशिश की, लेकिन मैं इस त्रुटि को जारी रखता हूं।

Mysql_fetch_assoc (): प्रदान की गई तर्क एक मान्य MySQL परिणाम संसाधन / url / पर पंक्ति 41 पर नहीं है 

  यदि ($ _POST [सबमिट करें] == "सबमिट करें") {$ sql = "तालिका में शामिल करें (` सामग्री`, `उपयोगकर्ता आईडी`,` टीटीएमई`) मूल्य ('$ _POST) [सामग्री] ',' '। $ User_id।' ',' ".time ()।" ') "; $ Res = mysql_query ($ sql, $ लिंक) या मर (mysql_error ()); / * (लाइन 41 निम्नलिखित है) * / जबकि ($ result = mysql_fetch_assoc ($ res)) {}}

मैंने त्रुटि को छूने की कोशिश की (कोई त्रुटि केवल चेतावनी छापती है ), मैंने क्वेरी को बदलने की कोशिश की, जो कुछ मैं सोच सकता था यह कोड ठीक काम करता है - यह क्लिक पर सम्मिलित करता है, सब कुछ ठीक है, सिर्फ यह चेतावनी दिख रही है। _। '

कोई भी विचार?

mysql_query ()

रिटर्न वैल्यू

सेलेक्ट के लिए, "पोस्ट-टेक्स्ट" आइटमप्रॉप = "टेक्स्ट">

अन्य प्रकार के एसक्यूएल स्टेटमेंट्स, INSERT, अद्यतन, डेलेटेड, ड्रॉप, आदि के लिए, IISL, आदि, mysql_query () त्रुटि पर सफलता या गलत पर TRUE देता है।

लौटा परिणाम संसाधन mysql_fetch_array (), और परिणाम तालिकाओं से निपटने के लिए, डेटा।

DELETE, INSERT, REPLACE, या UPDATE कथन से कितनी पंक्तियों को प्रभावित किया गया है यह जानने के लिए SELECT कथन या mysql_affected_rows () के लिए कितनी पंक्तियां लौटाई गईं, यह जानने के लिए mysql_num_rows () का उपयोग करें। / P> < P> mysql_query () भी असफल हो जायेगी और लौटाएगा यदि उपयोगकर्ता को क्वेरी द्वारा संदर्भित तालिका (ए) तक पहुंचने की अनुमति नहीं 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 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.
