Which dynamic management view provides details about SQL commands running in the data warehouse?

• A. sys.dm_exec_connections
• B. sys.dm_exec_sessions
• C. sys.dm_exec_query_stats
• D. sys.dm_exec_requests

Answer: (D)

The key idea is to see what is actively executing in the data warehouse right now. The dynamic management view that shows each current request, including details like the session, start time, status, and the command being executed, is the one you want. If you need the actual SQL text, you can retrieve it by joining this view with sys.dm_exec_sql_text using the sql_handle, which gives you the exact statements in flight. This view also provides blocking and wait information, helping you diagnose long-running queries or contention. The other views serve different purposes: one focuses on who is connected, another on session-level info, and another on aggregated performance data for queries that have already completed. They don’t reflect the live running commands in the same way, so they aren’t the best fit for viewing currently executing SQL in the data warehouse.
