Hi everyone, Today, whenever I want to gather the list of ports and their connections I use the following SQL query: SELECT ro1.name AS obj1, p1.label as p1_desc, p1.name AS port1, Link.cable, p2.name AS port2, p2.label as p2_desc, ro2.name AS obj2 FROM RackObject AS ro1 JOIN Port AS p1 ON(ro1.id=p1.object_id) JOIN Link ON(p1.id=Link.porta) JOIN Port AS p2 ON(Link.portb=p2.id) JOIN RackObject AS ro2 ON(p2.object_id=ro2.id) WHERE ro1.name like '%CF129%' or ro2.name like '%CF129%' ORDER BY obj1, port1; However, this query does not get the list of unused ports. Does anyone know how to accomplish this? BR! Lucas -- "Antes teníamos hambre y mirábamos el reloj para saber qué hora era. Ahora miramos el reloj para saber si tenemos hambre." -- Ernesto Sábato
