command

问题 Which is more proper to call INSERT/UPDATE/DELETE statements? Command or query?

Just a question from a mid-level web application developer who was also an communications major and is one who enjoys specificity. :) 回答1: The generic term for a INSERT ,

问题 I am trying to execute the following code in Python 2.6.5. What I want to do is show a main window with an 'Applications' menu. I want the menu to have a series of commands which should correspond to the keys of the Apps dictionary. When I click the command, I would like the default web browser to open and navigate to the url in the Apps dictionary for that particular key. Instead, when I execute the code the browser is opening to the first url in the Apps dictionary without any clicking.
