mysql, want like update tablename case fielda when value1 set fieldx0=xxx,fieldx1=bbb,fieldx2=ccc ... when value2 set fieldy0=yyy,fieldy1=eee,fieldy2=fff ... end what right , simple syntax it? thank much. it should written way: update tablename set fieldx = case when fielda = 'value1' 'xxx' else fieldx end, fieldy = case when fielda = 'value2' 'yyy' else fieldy end fielda in ('value1', 'value2'); note that: wrote else part way, because default else null if condition of case expression not valid, set original value not null value.

i understand how solve recurrence relations when not involve additional looping i.e.: int recursive_method(int n){ if(n == 1){ return 1; } constant statement; recursive_method(n-1); return n; } my problem comes when trying solve recurrences inside of loops following: int recursive_method(int n){ if(n == 1){ return 1; } for(int = 1; i<n; i++){ constant statement; recursive_method(n-1); } return n; } when trying set recursive relation problem above t(n) = 1 if n<2; sum(from i=1 n){t(n-1) + c} if n>=2 so in other words sum of costs 1 n? if not, how go thinking problem this? the expression have t(n) in recursive case right, can simplified. in particular, notice work done in sum independent of summation index, can rewrite sum i=1 n { t(n-1) + c } as nt(n - 1) + cn so you'll end with t(n) = 1 (if n ≤ 1) t(n) = nt(n - 1) ...

i'm trying understand how std::move simple example (below). i'm trying move contents of p1 p2, p1 empty after that, doesn't happen though. i guess i'm not using std::move properly. appreciate lot if explain me. #include <iostream> #include <utility> int main() { int * p1 = new int[10]; for(int = 0; < 10; ++i) p1[i]=i; // moving contents of p1 p2 int * p2 = std::move(p1); // expeting p1 empty it's not... if(p1 != null) std::cout << "i'm not empty\n"; // prints i'm not empty } the move function not guaranteed clear contents of source object. is, however, guaranteed left in such state can safely destroy or assign new value it.

i have class decorates methods using decorator library. specifically, class subclasses flask-restful resources, decorates http methods httpauth.httpbasicauth().login_required() , , sensible defaults on model service. on subclasses want decorator applied; therefore i'd rather remove add in subclasses. my thought have private method operations , public method decorated. effects of decoration can avoided overriding public method call private 1 , not decorating override. mocked example below. i curious know if there's better way this. there shortcut 'cancelling decorators' in python gives effect? or can recommend better approach? some other questions have suitable answers this, e.g. is there way function decorator has wrapped? . question broader design - interested in any pythonic way run operations in decorated methods without effects of decoration. e.g. example 1 such way there may others. def auth_required(fn): def new_fn(*args, **kwargs): pr...

we have asp.net ( silverlight) lob web application developed using .net 4. have rid of current authentication mechanism , implement new one. think have 2 options here: 1> forms authentication using membership provider ( available in .net 4) 2> asp.net identity ( not available in .net 4. have update target framework 4.5 or latter) i have gone through article here describes difference between these 2 , based on understanding 2 major differences are: 1> can configured identity framework use social credentials. 2> identity framework code can unit tested. we have lob application. likelihood of allowing users use social credential login our application very less. looking suggestion whether worthwhile spend time , implement identity framework authentication.
