System views supported in Synapse SQL

Links to the documentation for T-SQL statements supported in Synapse SQL.

Note

Synapse serverless SQL pool supports SQL Server catalog views only.

Dedicated SQL pool and serverless SQL pool catalog views

Dedicated SQL pool dynamic management views (DMVs)

SQL Server DMVs applicable to dedicated SQL pool

The following DMVs are applicable to dedicated SQL pool, but must be executed by connecting to the master database.

SQL Server catalog views

SQL Server DMVs available in dedicated SQL pool

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

SQL pool 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:
