sql - XACT_ABORT OFF ACID incompatible? -

-

i'm new here please gentle! :) ok, i've got sql server community/world 2 years (sql server dev , dba - 2005+ versions) , have discovered acid theory , wondering how hell sql server acid compatible? default comes xact_abort off option, right? , here's example msdn :

    if object_id(n't2', n'u') not null         drop table t2;     go     if object_id(n't1', n'u') not null         drop table t1;     go     create table t1         (a int not null primary key);     create table t2         (a int not null references t1(a));     go     insert t1 values (1);     insert t1 values (3);     insert t1 values (4);     insert t1 values (6);     go     set xact_abort off;     go     begin transaction;     insert t2 values (1);     insert t2 values (2); -- foreign key error.     insert t2 values (3);     commit transaction;     go  select * t2;

and result set:

a 1 3

where atomicity in case? did got whole acid theory wrong perhaps?

p.s.:the reason ask not because of acid property because have struggled many times in past xact_abort option , when gets combined clr code app via odbcs connections- off topic :)

yep, right. when used that, xact_abort off , without try/catch blocks, transactions in sql server pretty useless.

you should use xact_abort_on , try/catch blocks make transactions safe.

in case try/catch work xact_abort off:

    set xact_abort off;     go     begin try         begin transaction;         insert t2 values (1);         insert t2 values (2); -- foreign key error.         insert t2 values (3);         commit transaction;     end try     begin catch         rollback;     end catch       go

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
