SQL Select MaxID
Hello Folks, I would like to know if someone know how to select a max ID inside an view sql.
I've 5 tables with inner join (clientes, contactos, conductores, servicios and vehiculos)
I just one row for each client in all tables, LESS vehiculos table, because one cliente can have one or more car.
So when I called this sql, I need to select the last ID for an specific client in vehiculos table.
When I call this procedure I received 4 rows for an specific client, but I need to select the last row so the last one.
Someone know what I requesting??
I attached a jpg to see what I've
Thanks to everyone for any help

What makes an ID the "last" one?
post your query which gives you 4 rows for a specific client.
I think that your joins are wrong.
I think that your joins are wrong.
This should do:
Kindly replace All_tables with all tables with JOIN conditions
and all_other_columns with required columns.
It would be better if you provide your current query for easier modification

SELECT all_other_columns
from (
SELECT all_other_columns, Row_number() over ( partition by vehiculos.client order by some_datetimecol desc) rnum
from All_tables) temp
where rnum = 1
you have one or multiple cars against one client. so no of rows will be equal to the no of cars.
so get one car from the vehicle table against one client and then join other tables.
so your query will be like this

so your query will be like this
SELECT CLIENTES.*, Vehicle.Column FROM CLIENTES
CROSS APPLY (SELECT TOP 1 Vehicle FROM Vehiculos WHERE CLIENTES.ClientID = Vehiculos. ClientID) AS Vehicle
