sql - MySQL comparison with null value -

-
i have column called code in mysql table can null. have rows code='c' want ignore in select result set. can have either code=null or code!='c' in result set. the following query not return row code null: select * table code!='c' but query works expected , know right way it. select * table code null or code!='c' my question why having code!='c' not return rows code=null? 'c' not null. comparing no value character here. can throw light why doesn't work way? in mysql, null considered 'missing, unknown value', opposed no value. take at mysql reference on null . any arithmetic comparison null not return true or false, returns null instead., so, null != 'c' returns null , opposed returning true. any arithmetic comparison 'null' return false. check in sql: select if(null=123,'true','false') to check null values need use is null & is not null operator.

javascript - Where should I put the Collection instance in Backbone.js? -

-
is best place in global object or within view instance? (i'm thinking if place on global such as: window.todos = new todos() , pollute global object if there lot of collections; however, putting inside view may make things bit confusing) based on experience, best way place it? i think depends on application. have done establish namespace application, , put collections there, views: // namespace application var app = {}; // collection classes within namespace app.todos = backbone.collection.extend({ ... }); // , collection instances in namespace singletons app.todos = new app.todos(); for large application, might go further, establishing sub-namespaces model classes, view classes, router classes, , application instances. there few advantages this, though none of them crucial: having collections available in app namespace allows them referenced multiple views if necessary when debugging, have access collections in console establishing new namespace applic

java - Why is my ArrayList length 0 in my mouseClicked() function? -

-
in processing program, added object global arraylist called items in draw function. here class. class obj { string name; obj(string name) { self.name = name; } } here draw function. void draw () { items.add(new obj("bob")); } i tried printing size of items in mouseclicked() function console, keep getting 0. void mouseclicked () { print(items.size()); } why? the arraylist declared @ top of file after class: arraylist<obj> items = new arraylist<obj>(); there couple of things aren't quite there yet: self.name = name; should this.name = name; you're creating tons of objects (based on framerate), checking size of array in mousecliked() (also might want use println() instead). try this: arraylist<obj> items = new arraylist<obj>(); void setup(){ } void draw () { } void mouseclicked () { items.add(new obj("bob")); println("items size: " + items.size());

Git rebase (Merge Squash) my feature branch onto another branch -

i'm looking git command me feature branches when they're ready go master. git command squash changes on branch single commit on top of master. today with: git rebase origin/master git rebase -i head~4 where 4 number of commits squash. however, requires me know how many commits have. today running: git log head...origin/master and counting commits. i feel though there should better way this. or how else it, too? all have is: git checkout feature_branch git rebase master git checkout master git merge --squash feature_branch as docs git merge --squash say: produce working tree , index state if real merge happened (except merge information), not make commit or move head, nor record $git_dir/merge_head cause next git commit command create merge commit. allows create single commit on top of current branch effect same merging branch (or more in case of octopus). after that, can git commit changes staged.

android - use one webview replace with the listview? -

all, developing app "forum client", use webview each item in listview showing post list, there pics, texts , attachments can downloaded user. work, webview heavy component, need lots of system resources. have find method show post list. found this question same problem, , last post author said, use "one webview bunch of divs rendering individual contents", cannot it, so, did mean? i think meant should html showing in different webviews in each listview item, wrap each in div tag, show in 1 single webview user can scroll. should better performance since have 1 webview on-screen (and in memory) @ 1 time, rather 1 each visible row take lot of memory.
