Ci sono due operazioni diverse per controlarli
Prima per numeri doppi prova:
SELECT numeroprotocollo, COUNT(*) AS cnt FROM table GROUP BY numeroprotocollo HAVING cnt >1;
poi per i buchi:
SELECT t1.numeroprotocollo, t2.numeroprotocollo FROM table t1 LEFT JOIN table t2 ON t1.numeroprotocollo=t2.numeroprotocollo-1 WHERE t2.numeroprotocollo IS NULL;
