php - MySQL issue with UPDATE numbers -

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 1 उत्तर

    मैं करने की कोशिश कर रहा हूँ PHP के साथ एक बहुत सरल अद्यतन, इस तरह: 

      $ nlk = $ lk + "1"; Mysql_query ("पोस्ट्स को अपडेट करें = '"। $ Nlk "" WHERE id =' "। $ Cid।" '") या मरने (mysql_error ());   
      $ lk  एक फ़ील्ड  जैसा  से प्राप्त है, जो कि डिफ़ॉल्ट  0  है  $ cid  एक  आईडी  क्षेत्र से एक मान है, जो कि  auto_increment  पर है।  
     मुझे यह त्रुटि मिलती है:  
     
     आपके SQL सिंटैक्स में एक त्रुटि है; पास के 'जैसे =' 1 'WHERE id =' 45 '' पंक्ति 1 पर उपयोग करने के लिए सही सिंटैक्स के लिए आपके MySQL सर्वर संस्करण से संबंधित मैन्युअल की जांच करें   
     यहां समस्या क्या है?   
     
     
     इस का उपयोग करें (कॉलम नाम के आसपास जोड़ा गया टिक ( `)):  
      mysql_query ("अद्यतन पोस्ट्स सेट करें" = '"। $ Nlk।"' WHERE id = '"। $ Cid।"' ") या मर (mysql_error ());   
     बेहतर अभी तक, तालिका / स्तंभ नामों के रूप में उपयोग न करें।

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
