SQL Server catalog views

SQL Server DMVs available in SQL Data Warehouse

SQL Data Warehouse exposes many of the SQL Server dynamic management views (DMVs). These views, when queried in SQL Data Warehouse, are reporting the state of SQL Databases running on the distributions.

SQL Data Warehouse and Analytics Platform System's Parallel Data Warehouse (PDW) use the same system views. Each DMV has a column called pdw_node_id, which is the identifier for the Compute node.

Note

To use these views, insert ‘pdw_nodes_’ into the name, as shown in the following table:
