c# - Error in MySQL syntax when adding object to objectcontext -

-

i seem have trouble adding objects tables have 'n n' relationship.

tables defined follows:

table a

  • id (primary)
  • ...
  • ...
  • ...

table b

  • id (primary)
  • ...
  • ...
  • ...

table c

  • tablea_id (index)
  • tableb_id (index)

so table c links table , b, ids. using entity framework have object tablea containing entity collection of tableb entities.

however when add existing object of type tableb tablea.tablebs entity collection property, receive exception:

you have error in sql syntax; check manual corresponds mysql server version right syntax use near '(select\n tablec.tablea, \n ' @ line 1

it seems i'm trying normal / common thing, i've not been successful getting work.

c# code:

var database = new databaseentities(); var tableaobject = database.singleordefault(e => e.id == 1); var tablebobject = database.singleordefault(e => e.id == 1);  tablea.tablebentities.add(tablebobject); database.savechanges();

apparently i'm doing wrong, question is, how should add object table 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...
