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 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)
