Am a beginner to SQL Server usage. What is the difference between using DBCC MEMORYSTATUS to get the memory usage detail (i.e. % of memory usage), and using columns from sys.dm_os_sys_info ? I heard that the former is more accurate. Is it true? If yes,
why? Can you please elaborate from T-SQL perspective (am not going to use Memory Monitor, I want to do it through queries/SPs)?
