codeVet Year_Inv nro_inv type_inv

000 23 63509 G

046 23 71490 G

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

75569

G

23

75978

G

046

23

76078

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
