DMV di SQL Server disponibili nel pool SQL dedicato (in precedenza SQL Data Warehouse)

Il pool SQL dedicato (in precedenza SQL Data Warehouse) espone molte delle viste a gestione dinamica (DMV) di SQL Server. Queste viste, se sottoposte a query nel pool SQL dedicato (in precedenza SQL Data Warehouse), segnalano lo stato dei database SQL in esecuzione nelle distribuzioni.

Il pool SQL dedicato (in precedenza SQL Data Warehouse) e Parallel Data Warehouse (PDW) usano le stesse viste 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:
