Query a SQL server to find the progress of a database restore

This just came in from a co-worker. Too valuable not to share!

In case you might want to monitor the progress of a database restore on your SQL server, this query shows the progress in percentage, elapsed time, etc…

SELECT
	r.session_id,
	r.command,CONVERT(NUMERIC(6,2),r.percent_complete) AS [Percent Complete],
	CONVERT(VARCHAR(20),DATEADD(ms,r.estimated_completion_time,GetDate()),20) AS [ETA Completion Time],
	CONVERT(NUMERIC(10,2),r.total_elapsed_time/1000.0/60.0) AS [Elapsed Min],
	CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0) AS [ETA Min],
	CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0/60.0) AS [ETA Hours],
	CONVERT(VARCHAR(1000),(SELECT SUBSTRING(text,r.statement_start_offset/2,
		CASE WHEN r.statement_end_offset = -1 THEN 1000 ELSE (r.statement_end_offset-r.statement_start_offset)/2 END)
		FROM sys.dm_exec_sql_text(sql_handle)))
FROM sys.dm_exec_requests r WHERE command IN ('RESTORE DATABASE','BACKUP DATABASE')

With that, you can really tell how far along a SQL restore is!
