sql - Creating a Stored Procedure -

-

i trying create stored procedure allow me update actualarrivaldate , actualdeparturedate in tripstop table stoptypecode = drop in tripstoporder table.

create proc spupdatetable @orderid int, @arrivaldate datetime, @departuredate datetime   begin      begin transaction    select * dbo.tripstoporder    join dbo.tripstop on dbo.tripstoporder.tripstopid = dbo.tripstop.tripstopid    orderid = ''and stoptypecode ='drop'

once find record need grab tripstopid , pass update statement. not sure how this...can use temp table run select statement pick tripstopid?

   update dbo.tripstop set arrivaldate='',departuredate=''    tripstopid = ''  end commit

any ideas or suggestions appreciated. ~newbie~

instead of doing select , update, change clause in update statement:

where tripstopid = (select t.tripstopid tripstoporder o inner join tripstop t on o.tripstopid = t.tripstopid orderid = @orderid , stoptypecode = 'drop')

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
