在SQL SERVER中如何通过SQL语句获取服务器硬件和系统信息呢?下面介绍一下如何通过SQL语句获取处理器(CPU)、内存(Memory)、磁盘(Disk)以及操作系统相关信息。如有不足和遗漏,敬请补充。谢谢!
 
一:查看数据库服务器CPU的信息
 
---SQL 1:获取数据库服务器的CPU型号
 
EXEC xp_instance_regread 
'HKEY_LOCAL_MACHINE',
'HARDWARE\DESCRIPTION\System\CentralProcessor\0',
'ProcessorNameString';

 

 
---SQL 2:获取数据库服务器CPU核数等信息(只适用于SQL 2005以及以上版本数据库)
 
/*************************************************************************************
--cpu_count:指定系统中的逻辑 CPU 数
--hyperthread_ratio:指定一个物理处理器包公开的逻辑内核数与物理内核数的比.
-- 中可以表示每个虚拟插槽的核数。虚拟中[Physical CPU Count]其实
-- 表示虚拟插槽数
*************************************************************************************/
SELECT s.cpu_countAS [Loggic CPU Count]
,s.hyperthread_ratioAS [Hyperthread Ratio]
,s.cpu_count/s.hyperthread_ratioAS [Physical CPU Count] 
FROM sys.dm_os_sys_info s OPTION (RECOMPILE);

 

---SQL 3:获取服务器CPU核数(适用于所有版本)
 
CREATE TABLE #TempTable
(
[Index] VARCHAR(2000) ,
[Name] VARCHAR(2000) ,
[Internal_Value] VARCHAR(2000) ,
[Character_Value] VARCHAR(2000)
);
INSERTINTO #TempTable
EXEC xp_msver;
SELECTInternal_Value AS VirtualCPUCount
FROM#TempTable
WHERE Name = 'ProcessorCount';
DROP TABLE #TempTable;
GO

 

---SQL 4:在老外博客中看到一个计算CPU相关信息的SQL,不过虚拟机计算有点小问题,我修改了一下。
 
DECLARE @xp_msver TABLE (
[idx] [int] NULL
,[c_name] [varchar](100) NULL
,[int_val] [float] NULL
,[c_val] [varchar](128) NULL
)

INSERT INTO @xp_msver
EXEC ('[master]..[xp_msver]');;

WITH [ProcessorInfo]
AS (
SELECT ([cpu_count] / [hyperthread_ratio]) AS [number_of_physical_cpus]
,CASE 
WHEN hyperthread_ratio = cpu_count
THEN cpu_count
ELSE (([cpu_count] - [hyperthread_ratio]) / ([cpu_count] / [hyperthread_ratio]))
END AS [number_of_cores_per_cpu]
,CASE 
WHEN hyperthread_ratio = cpu_count
THEN cpu_count
ELSE ([cpu_count] / [hyperthread_ratio]) * (([cpu_count] - [hyperthread_ratio]) / ([cpu_count] / [hyperthread_ratio]))
END AS [total_number_of_cores]
,[cpu_count] AS [number_of_virtual_cpus]
,(
SELECT [c_val]
FROM @xp_msver
WHERE [c_name] = 'Platform'
) AS [cpu_category]
FROM [sys].[dm_os_sys_info]
)
SELECT [number_of_physical_cpus]
,[number_of_cores_per_cpu]
,[total_number_of_cores]
,[number_of_virtual_cpus]
,LTRIM(RIGHT([cpu_category], CHARINDEX('x', [cpu_category]) - 1)) AS [cpu_category]
FROM [ProcessorInfo]

 

---查看虚拟机CPU信息
 
DECLARE @xp_msver TABLE (
[idx] [int] NULL
,[c_name] [varchar](100) NULL
,[int_val] [float] NULL
,[c_val] [varchar](128) NULL
)

INSERT INTO @xp_msver
EXEC ('[master]..[xp_msver]');;

WITH [ProcessorInfo]
AS (
SELECT ([cpu_count] / [hyperthread_ratio]) AS [number_of_physical_cpus]
,[hyperthread_ratio] AS [number_of_cores_per_cpu]
,[cpu_count] AS [total_number_of_cores]
,[cpu_count] AS [number_of_virtual_cpus]
,(
SELECT [c_val]
FROM @xp_msver
WHERE [c_name] = 'Platform'
) AS [cpu_category]
FROM [sys].[dm_os_sys_info]
)
SELECT [number_of_physical_cpus]
,[number_of_cores_per_cpu]
,[total_number_of_cores]
,[number_of_virtual_cpus]
,LTRIM(RIGHT([cpu_category], CHARINDEX('x', [cpu_category]) - 1)) AS [cpu_category]
FROM [ProcessorInfo]

 

 
二:查看数据库服务器内存的信息
 
能否通过SQL语句获取服务器的物理内存大小?内存条型号?虚拟内存大小?内存使用情况? 目前我所知道的只能通过SQL语句获取服务器物理内存大小,内存的使用情况。 至于内存条型号,系统虚拟内存大小,暂时好像还无法通过SQL语句获取。
 
查看服务器的物理内存情况
 
如下所示,从sys.dm_os_sys_info里面获取的physical_memory_in_bytes 或physical_memory_kb 的值总是低于实际物理内存。暂时不清楚具体原因(还未查到相关资料),所以计算大小有出入,要获取实际的物理内存,就必须借助CEILING函数。
 
 
--SQL 1:获取数据库服务器物理内存数(适用于所有版本)
 CREATE TABLE #TempTable
(
[Index] VARCHAR(2000) ,
[Name] VARCHAR(2000) ,
[Internal_Value] VARCHAR(2000) ,
[Character_Value] VARCHAR(2000)
);
INSERTINTO #TempTable
EXEC xp_msver;
SELECTInternal_Value/1024 AS PhysicalMemory
FROM#TempTable
WHERE Name = 'PhysicalMemory';
DROP TABLE #TempTable;
GO

 

---SQL 2:适用于SQL Server 2005、SQL Server 2008
 SELECT CEILING(physical_memory_in_bytes*1.0/1024/1024/1024)AS [Physical Memory Size]
FROM sys.dm_os_sys_infoOPTION (RECOMPILE) 


SELECT physical_memory_in_bytes*1.0/1024/1024/1024
 , physical_memory_in_bytes AS [Physical Memory Size]
FROM sys.dm_os_sys_infoOPTION (RECOMPILE)
---SQL 3:适用于SQL Server 2012 到 SQL Server 2014

 SELECT CEILING(physical_memory_kb*1.0/1024/1024) AS [Physical Memory Size]
FROM sys.dm_os_sys_infoOPTION (RECOMPILE);

 

---SQL 4:适用于SQL Server 2008以及以上的版本:查看物理内存大小,已经使用的物理内存以及还剩下的物理内存。
 
SELECTCEILING(total_physical_memory_kb * 1.0 / 1024 / 1024)AS [Physical Memory Size] 
 ,CAST(available_physical_memory_kb * 1.0 / 1024 / 1024 
AS DECIMAL(8, 4)) AS [Unused Physical Memory]
 ,CAST(( total_physical_memory_kb - available_physical_memory_kb ) * 1.0
/ 1024 / 1024 AS DECIMAL(8, 4))AS [Used Physical Memory]
 ,CAST(system_cache_kb*1.0 / 1024/1024 AS DECIMAL(8, 4))AS [System Cache Size]
FROMsys.dm_os_sys_memory

 

 
三:查看数据库服务器硬盘的信息
 
如下所示,我们可以通过下面脚本获取服务器的各个磁盘的使用情况。但是无法获取磁盘的型号、转速之类的信息。
 
SET NOCOUNT ON


DECLARE @Result INT;
DECLARE @objectInfo INT;
DECLARE @DriveInfo CHAR(1);
DECLARE @TotalSize VARCHAR(20);
DECLARE @OutDrive INT;
DECLARE @UnitMB BIGINT;
DECLARE @FreeRat FLOAT;

SET @UnitMB = 1048576;


 

--创建临时表保存服务器磁盘容量信息
CREATE TABLE #DiskCapacity
(
[DiskCD] CHAR(1) ,
FreeSize INT ,
TotalSize INT
);

INSERT #DiskCapacity([DiskCD], FreeSize ) 
EXEC master.dbo.xp_fixeddrives;

EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;

EXEC sp_configure 'Ole Automation Procedures', 1;
RECONFIGURE WITH OVERRIDE;


EXEC @Result = master.sys.sp_OACreate 'Scripting.FileSystemObject',@objectInfo OUT;

DECLARE CR_DiskInfo CURSOR LOCAL FAST_FORWARD
FOR 
SELECTDiskCD FROM #DiskCapacity
ORDER by DiskCD


OPEN CR_DiskInfo;

FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo

WHILE @@FETCH_STATUS=0
BEGIN

EXEC @Result = sp_OAMethod @objectInfo,'GetDrive', @OutDrive OUT, @DriveInfo


EXEC @Result = sp_OAGetProperty @OutDrive,'TotalSize', @TotalSize OUT


UPDATE #DiskCapacity
SET [email protected][email protected]
WHERE [email protected]

FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo

END

CLOSE CR_DiskInfo
DEALLOCATE CR_DiskInfo;

EXEC @Result=sp_OADestroy @objectInfo

EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;

EXEC sp_configure 'Ole Automation Procedures', 0;
RECONFIGURE WITH OVERRIDE;

EXEC sp_configure 'show advanced options', 0
RECONFIGURE WITH OVERRIDE;



SELECT DiskCD AS [Drive CD] , 
 STR(TotalSize*1.0/1024,6,2) AS [Total Size(GB)] ,
 STR((TotalSize - FreeSize)*1.0/1024,6,2) AS [Used Space(GB)] ,
 STR(FreeSize*1.0/1024,6,2) AS [Free Space(GB)] ,
 STR(( TotalSize - FreeSize)*1.0/(TotalSize)* 100.0,6,2)AS [Used Rate(%)],
 STR(( FreeSize * 1.0/ ( TotalSize) ) * 100.0,6,2)AS [Free Rate(%)]
FROM #DiskCapacity;

DROP TABLE #DiskCapacity;

 

四:查看操作系统信息
 
通过下面SQL语句,我们可以查看操作系统版本、补丁、语言等信息
 
--创建临时表保存语言版本信息
CREATE TABLE #Language
(
[LanguageDtl]NVARCHAR(64) ,
[os_language_version]INT
);



INSERT INTO #Language
SELECT 'English - United States',1033 UNION ALL
SELECT 'English - United Kingdom' ,2057 UNION ALL
SELECT 'Chinese - People''s Republic of China',2052 UNION ALL
SELECT 'Chinese - Singapore',4100 UNION ALL
SELECT 'Chinese - Taiwan' ,1028 UNION ALL
SELECT 'Chinese - Hong Kong SAR',3076 UNION ALL
SELECT 'Chinese - Macao SAR',5124;


WITH SystemVersion(SystemInfo,ReleaseNo)
AS
(
SELECT'Windows 10' ,
'10.0*'
UNION ALL
SELECT'Windows Server 2016 Technical Preview' ,
'10.0*'
UNION ALL
SELECT'Windows 8.1' ,
'6.3*'
UNION ALL
SELECT'Windows Server 2012 R2' ,
'6.3'
UNION ALL
SELECT'Windows 8' ,
'6.2'
UNION ALL
SELECT'Windows Server 2012' ,
'6.2'
UNION ALL
SELECT'Windows 7' ,
'6.1'
UNION ALL
SELECT'Windows Server 2008 R2' ,
'6.1'
UNION ALL
SELECT'Windows Server 2008' ,
'6.0'
UNION ALL
SELECT'Windows Vista' ,
'6.0'
UNION ALL
SELECT'Windows Server 2003 R2' ,
'5.2'
UNION ALL
SELECT'Windows Server 2003' ,
'5.2'
UNION ALL
SELECT'Windows XP 64-Bit Edition' ,
'5.2'
UNION ALL
SELECT'Windows XP' ,
'5.1'
UNION ALL
SELECT'Windows 2000' ,
'5.0'
)

SELECT s.SystemInfo 
,w.windows_service_pack_level
,l.LanguageDtl
FROM sys.dm_os_windows_info w
INNER JOIN SystemVersion s ON w.windows_release=s.ReleaseNo
INNER JOIN #Language l ON l.os_language_version = w.os_language_version;


DROP TABLE #Language;

 

注意:
 
1:如上所示,临时表#Language的数据此处只列了几条常用的数据,如需全部数据,参考https://msdn.microsoft.com/zh-CN/goglobal/bb964664.x自行补充。
 
2:操作的版本信息的数据来源于https://msdn.microsoft.com/zh-CN/library/ms724832(VS.85).aspx
 
有可能出现不同操作系统具有相同Version number值,例如Windows 7 和Windows Server 2008 R2的Version numberd都为6.1。导致下面查询结果出现多条记录(如下所示)。一般要酌情判断(如果生产服务器都为Windows服务器,可以剔除Windows XP、Windows 7这类数据)。
