sql server - datediff between multiple records in SQL -

-

i have 1 scenario want count if date difference between 2 dates <=14 days.that in first table have filter records 1 value of date1 values <=14 days of date2.

for ex:  q1="select date1 date1_table";  q2="select date2 date2_table";   simple query :   select      count(*)         date1_table datediff(dd,date1,(select date2 date2_table))<=14

but have multiple records in both tables,but want choose record having difference count >0.so,it throwing error subquery returned more 1 record.i want solutions this.i using sql server 2008

note:i can't use join here.because wanted results 2 different queries. in advance.

you can use top 1 clause in query..

select top 1 *     date1_table       datediff(dd,date1,(select date2 date2_table))<=14

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.
