sql - Limit the number of rows per ID -

-

i trying limit number of rows per case 5 rows. cases have 1 or 2 rows have 15 or more.

this example of stored procedure using count number of rows per case.

select     row_number() over(partition rce.reportruncaseid order rce.reportruncaseid) row, rce.reportruncaseid caseid, year(rce.ecodate) ecoyear         phdrpt.reportcaselist rcl inner join                   phdrpt.rptcaseeco rce on rce.reportid = rcl.reportid , rce.reportruncaseid = rcl.reportruncaseid group rce.reportid, rce.reportruncaseid, year(rce.ecodate) order rce.reportruncaseid, year(rce.ecodate)

here screenshot of stored procedure produces: screenshot

i have tried use clause not allow me place window function after clause. not recognize "row" alias.

is there way count number or rows per case (instead of window function) can use clause? or there way limit records per case 5 using existing stored procedure?

thank in advance help.

you can wrap statement in cte since sql server supports it.

with records (     select  row_number() over(partition rce.reportruncaseid                                order rce.reportruncaseid) row,              rce.reportruncaseid caseid,              year(rce.ecodate) ecoyear        phdrpt.reportcaselist rcl                  inner join phdrpt.rptcaseeco rce                      on  rce.reportid = rcl.reportid                          , rce.reportruncaseid = rcl.reportruncaseid     group   rce.reportid, rce.reportruncaseid, year(rce.ecodate) ) select caseid, ecoyear   records  row <= 10 order  caseid, ecoyear

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...
