Dedicated SQL pool (formerly SQL DW) exposes many of the SQL Server dynamic management views (DMVs). These views, when queried in dedicated SQL pool (formerly SQL DW), are reporting the state of SQL Databases running on the distributions.
Dedicated SQL pool (formerly SQL DW) and 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:
