mysql - Getting minimum value for three columns group by a single column in a single table -

-

i have single table , table structure this:

unique_id     vendor_name      price1     price2     price3    code   1             vendor 1         0.0012     0.0014     0.0054     125 2             vendor 2         0.0015     0.0016     0.0050     125 3             vendor 3         0.0011     0.0019     0.0088     125 4             vendor 1         0.0025     0.0024     0.0034     126 5             vendor 2         0.0043     0.0019     0.0065     126 6             vendor 3         0.0019     0.0085     0.0082     126

i have fetch min price each price column group code. , expected output follows:

code          price1          price2      price3     vendor price1      vendor price 2      vendor price 3  125           0.0011          0.0014      0.0050     vendor3                vendor1                 vendor 2  126           0.0019          0.0019      0.0034     vendor3                vendor2                 vendor 1

so mysql query fetch records this? , have make query fetch maximum , second highest value table , there may number of rows single code.

my data in sql fiddle.

in second highest value case output should as:

code          price1          price2      price3     vendor price1      vendor price 2      vendor price 3 125           0.0012          0.0016      0.0054     vendor1                vendor2                 vendor 1  126           0.0025          0.0024      0.0065     vendor1                vendor1                 vendor 2 

select     data.*,     v1.vendor_name 'vendor price1',     v2.vendor_name 'vendor price2',     v3.vendor_name 'vendor price3'     (         select             code,             min(price1) price1,             min(price2) price2,             min(price3) price3                     tbl         group code     ) data     left join     (         select              min(vendor_name) vendor_name,             code                     tbl                     price1 =              (                 select                     min(price1)                                     tbl t                                     t.code = tbl.code             )         group code     ) v1 on data.code = v1.code     left join     (         select              min(vendor_name) vendor_name             code                     tbl                     price2 =              (                 select                     min(price2)                                     tbl t                                     t.code = tbl.code             )         group code     ) v2 on data.code = v2.code     left join     (         select              min(vendor_name) vendor_name             code                     tbl                     price3 =              (                 select                     min(price3)                                     tbl t                                     t.code = tbl.code             )         group code     ) v3 on data.code = v3.code

even though query looks pretty big, joins repeated 3 times.

update updated query removing limit , adding min(vendor_name) vendor_name instead of vendor_name.

output

| code | price1 | price2 | price3 | vendor price1 | vendor price2 | vendor price3 | ----------------------------------------------------------------------------------------------- |  125 | 0.0011 | 0.0014 | 0.0050 |          vendor 3 |          vendor 1 |          vendor 2 | |  126 | 0.0019 | 0.0019 | 0.0034 |          vendor 3 |          vendor 2 |          vendor 1 |

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
