这篇文章主要介绍了SQL语句实现查询SQL Server内存使用状况,本文直接给出实现代码,需要的朋友可以参考下

				?

									SELECT type,--Clerk的类型  

									sum(virtual_memory_reserved_kb)as vm_Reserved_kb,--保留的内存  

									sum(virtual_memory_committed_kb)as vm_Committed_kb,--提交的内存  

									sum(awe_allocated_kb)as awe_Allocated_kb,--开启AWE后使用的内存  

									sum(shared_memory_reserved_kb)as sm_Reserved_kb,--共享的保留内存  

									sum(shared_memory_committed_kb)as sm_Committed_kb,--共享的提交内存  

									sum(single_pages_kb)as SinlgePage_kb,-- Buffer Pool中的Stolen的内存  

									sum(multi_pages_kb)as MultiPage_kb-- MemToLeave的内存

									FROM sys.dm_os_memory_clerks 

									GROUP BY type ORDER BYtype

									--查询Buffer Pool/Memory To Leave

									SELECT

									 sum(virtual_memory_reserved_kb)AS [Reserved],

									 sum(virtual_memory_committed_kb)AS [Commit],

									 sum(virtual_memory_reserved_kb)/sum(virtual_memory_committed_kb) AS[Reserved/Commit],

									 sum(single_pages_kb)+sum(multi_pages_kb) AS [Stolen],

									 sum(virtual_memory_committed_kb)+sum(single_pages_kb)AS [Buffer Pool],

									 sum(multi_pages_kb) AS[MemToLeave],

									 SUM(awe_allocated_kb)AS [AWEAllocated]

									 FROM sys.dm_os_memory_clerks

									--查询SQLSERVER内存使用

									select * from sys.dm_os_process_memory
