我是靠谱客的博主酷酷烧鹅，最近开发中收集的这篇文章主要介绍SQL语句实现查询SQL Server内存使用状况，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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
