sql - Trying to get the next value in sequence from a postgres DB, with django -

-

I have defined a sequence in my database that I want to use in my own dengue application. I thought I could use the raw SQL method specified in the DNS document here:. My plan was to execute the following SQL statement: 

  choose the next ('winner')   
 Where the winning sequence is I want to get the next value Are from Here is my code: django.db Transaction from import connection ..... cursor = connection.cursor () result = cursor.exicute ("select next ('winner')")   
 The result is not always of any kind, it seems very simple and simple, but I am not able to do this work. I have tried in the interactive console with the same result. If I look into the connection.queries object, I see it:  
  {'time': '0.000', 'sql': "Choose the next ('winner')"}   
 The generated SQL is valid. Any ideas?  
 I am using:  
     
  •  Django 1.1  
  •  Python 2.6  
  •  Postgrass 8.3  
  •  Psycopg2  
  •  Mac OSX    
     
     
      cursor   Always  does not remove any returns.  
     To get a value from the SQL statement, you should see the  cursor.fetchone ()  (or  fetchall () ).  
     Note, though it does care that nothing has been done with Django, but the standard Python is SQL DB API.

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)
