sql server - Bulk insert not working for NULL data -

-

when inserting bulk data table csv file, not working, showing error lie :

bulk load data conversion error (type mismatch or invalid character specified codepage) row 2, column 9

column 9 value in csv file null..

how take care of this?

from amount of information i'd target table's particular field defined "not null". workaround issue have to:

a) modify csv-->add value field(s) have null

b) modify target table setting affected fields 'nullable':alter table [tblname] alter column [nulcolname] [vartype such int] null
in case go solution , want turn table's status alter again:
update [tblname] set [nulcolname]=-1000 [nulcolname] null avoid alter errors, alter table [tblname] alter column [nulcolname] [vartype such int] not null

c) pretty 'b' option bit more professional , faster: create temp table based on target table allowing nulls , fields, update temp table's null records after csv import "default value" , copy data target table


if i'm right issue , there's no option revise csv i'd go option 'c'

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...
