SQL Server DMV disponibili nel pool SQL dedicato
Il pool SQL espone molte delle viste a gestione dinamica (DMV) di SQL Server. Queste visualizzazioni, quando viene eseguita una query nel pool SQL dedicato, segnalano lo stato dei database SQL in esecuzione nelle distribuzioni.
Il pool SQL e il sistema parallelo di Analytics Platform Data Warehouse (PDW) usano le stesse visualizzazioni di sistema. Ogni DMV ha una colonna denominata pdw_node_id, che è l'identificatore del nodo di calcolo.
Nota
Per usare queste viste, inserire 'pdw_nodes_' nel nome, come mostrato nella tabella seguente:
