codeVet Year_Inv nro_inv type_inv
000 23 63509 G
046 23 71490 G
046 23 71490 H

Hi all
Suppose i have a table with this data
codeVet
Year_Inv
nro_inv
type_inv
000
23
63509
G
046
23
71490
G
046
23
71490
H
046
23
75569
G
046
23
75978
G
046
23
76078
G
With Sql i would get :
The nro Invoice for every CodeVet_vet excluding the nro_inv the have two or
more row (in this case the nro_inv 23-71490) ; so the result that i would
need, is
CodeVet Nro_inv
000 1
046 3
Thanks in advance
Gio
