sql - Select from table with dynamic compute name -

-

i want write query in name table dynamicaly compute. have code below. should put in 'magic code' region?

declare @mytablename nvarchar(100) = 'sch'           +  cast(@nowyear varchar(5))           +  'q'           +  cast(@nowquarter varchar(3))           +  '.[tvisits]'  -- magic code -- mytable = dosomething(@akttablename)    -- magic code --  select * mytable

i use ms sql server 2012

you need use dynamic sql -

declare        @nowyear int = 2013     , @nowquarter int = 1  declare @mytablename nvarchar(100) = '[sch'           +  cast(@nowyear varchar(5))           +  'q'           +  cast(@nowquarter varchar(3))           +  '].[tvisits]'  declare @sql nvarchar(max) = n'select * ' + @mytablename  exec sys.sp_executesql @sql

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
