tsql - SQL Server Row_number in odd/even number? -

-

i have question querying accounting data.

for example, sample data show below

table: table_test

date        amount   2013-01-01  12.00 2013-01-02  13.00

the output should this:

date        account        debit    credit 2013-01-01  abccompany     12.00 2013-01-01  vendorcompany           12.00 2013-01-02  abccompany     13.00 2013-01-02  vendorcompany           13.00

initially, think using union statement because may output sequece not important , sample sql show below

select      date 'date',      'abccompany' 'account',      amount 'debit',      '0' credit table_test  union  select     date 'date',      'vendorcompany' 'account',      '0' 'debit',      amount  credit table_test

output:

date        account        debit    credit 2013-01-01  abccompany     12.00 2013-01-02  abccompany     13.00 2013-01-01  vendorcompany           12.00 2013-01-02  vendorcompany           13.00

but seem after show output pic, mention wrong sequence quite important them.(used export system)

what came out mind using t-sql manipulate may provide flag isdebit , possible row_number(odd number in first sql, number on second sql union , made logic on it? possible?)

is able provide me idea how deal this?

something should work:

select  date 'date', 'abccompany' 'account', amount 'debit', '0' credit, row_number() on (order date) * 2 rn table_test union date 'date', 'vendorcompany' 'account', '0' 'debit', amount  credit, row_number() on (order date) * 2 + 1 table_test order rn

although more columns may needed in order by clauses make things unambiguous (it's tad tricky tell limited example you've given)

i've switched using union all since result sets produced distinct.

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
