i read here on so how : in c++ : not returning non-void function undefined behavior. ... analysis requires inspection of entire program, incompatible separate compilation, , not possible in general case ... from made out of several answers on page, difficult, , infact impossible sometimes, check presence of return statement in functions. not returning non-void function left undefined behavior c++ standard. however, heard in java, same thing reported error @ compile time. q. understanding correct ? , how java achieves same ? edit: clear, interested in understanding : if left undefined in c++ standard implementation difficulties related compiler, how java able achieve same. and if not difficult do, shouldn't c++ standard have defined error ? java refusing run programs, if return value. take following (stupid) method public boolean test() { boolean var=true; if(var) return true; } the method return true, java still refuse accept val

so have table need create view from, we'll call tableabc. thing table has 2 columns. column 1 we'll call c1 , it's char(25) column. easy enough. the tricky part next column....and need it. we'll call c2 , 600 bytes! why may ask? it's 600 characters because storing data in based on offsets. for instance: name1 size:15 beginning offset:1 ending offset:12 name2 size:45 beginning offset:13 ending offset: 49 so need store column based on offsets, , "offset named" need specific, ie name1/name2 (actually called different things, name1/name2 now) there 15 of these offsets. now i've done bit of oracle admin stuff, basic stuff. know sql server better way beyond im used doing, im looking challenge. views sorta new me. makes more difficult. i figure maybe substr function, like: select substr(c2, 1, 12) name1 table would work? i've not done stored procedures, maybe theirs better way? edit: so sample wise, (i need add different offsets) w

i'm making news archive. want news archive have several options. @ first want archive have option display news posted in year , option display news thats posted in category. these features both saved in database @ every post small php code can find posts created in e.g 2013. the problem is want make buttons in news archive. buttons can make user decide feature enabled or not (if understand i'm saying). want users have ability make sure posts of e.g 2013 appear on screen on same time posts of e.g sport news appear. making 2 features user enable, couldn't think of way linking them correct page. if click on specific year go article.php?year=2013 example. if want use other feature (category) it's impossible because send article.php?category=sport example , posts no longer searched on published year on category. i want make sure if 1 feature/option enabled other add &category=sport @ end of url url becomes article.php?year=2013&category=sport makes sure us

in org mode, if want format text monospace verbatim, i.e. ~...~ , if inside quotes: ~"..."~ , not formatted (left is). also, quotes reserved symbol, if so, mean?

i'm trying use activerecord best of it's ability , having trouble doing joins in way like. here how models set up: class model has_many :likes end class belongs_to :model belongs_to :user end class user has_many :likes end i likes 'model' object , there users made like. activerecord query is @model = model.find(params[:id]) @users = @model.likes.joins(:user) however, last line of code returns like, not user. there way use joins appropriately , want? thanks, you can has_many :through : class model has_many :likes has_many :users, :through => :likes end or can eager load users , join in ruby: @users = @model.likes.includes(:user).map(&:user)
