Question

After a Select Query I have the following table:

id  CN    SN    DC
1   null  null  null
1   1234  null  1245
1   null  2536  null
2   null  null  null
2   null  2596  null

I want make using select command in SQL SERVER something like:

id   CN    SN    DC
1    1234  2536  1245
2    null  2596  null

Can anyone help me with that, please?
Thank you!

Answer 1

Assuming you want the maximum value returned for each column:

select id, max(CN) as CN, max(SN) as SN, max(DC) as DC
from MyTable
group by id
