Sql Server 性能分析1 –查看数据库的相关信息

 

1.       在一台sql server 上操作，我们要尽过能的知道数据的相关信息，这是性能分析的根本。

查看能Sql Server 的相关信息，我们可以用Serverproperty来得到数据库的相关信息，以下是ServerProperty 的相关使用说明：

 

SERVERPROPERTY

 

Returns property information about the server instance.

 

语法：

Syntax

SERVERPROPERTY ( propertyname )

 

Arguments

propertyname

Is an expression containing the property information to be returned for the server. propertyname can be one of these values.

3 = Enterprise (returned for Enterprise, Enterprise Evaluation, and Developer)

Base data type: int

InstanceName

The name of the instance to which the user is connected.

Returns NULL if the instance name is the default instance, or invalid input or error.

Base data type: nvarchar

IsClustered

1 = True.
0 = False.

Base data type: int

LicenseType

Mode of this instance of SQL Server.

PER_SEAT = Per-seat mode
PER_PROCESSOR = Per-processor mode
DISABLED = Licensing is disabled.

Base data type: nvarchar(128)

MachineName

Windows NT computer name on which the server instance is running.

ServerName

Both the Windows NT server and instance information associated with a specified instance of SQL Server.

Base data type: nvarchar

 

例子：如要查询电脑名，Sql server 数据库实例名，数据库版本，数据类型，数据库级别（如升包等）

 

select

SERVERPROPERTY('MachineName') as N’Machine Name’,

serverproperty('Servername') as N’Server Name’,

SERVERPROPERTY('ProductVersion') N'Database Version',

SERVERPROPERTY ('Edition') N'Database Type',

SERVERPROPERTY('ProductLevel') N'Database Packs'

 

 

注意：@@Version 中的信息与 SERVERPROPERTY 中反映的信息是不一定相同的，查看Sql Server数据库的信息我们应该以SERVERPROPERTY 为准。

 

Select

cast(SERVERPROPERTY('MachineName')as varchar(10))  as N'Machine Name',

cast(SERVERPROPERTY('Servername') as varchar(20)) as N'Server Name',

cast(SERVERPROPERTY('ProductVersion') as varchar(10)) N'Database Version',

cast(SERVERPROPERTY ('Edition') as varchar(10)) N'Database Type',

cast(SERVERPROPERTY('ProductLevel')as varchar(10)) N'Database Packs'

 

Machine Name Server Name          Database Version Database Type Database Packs

------------ -------------------- ---------------- ------------- ----------

VS-HKMESDB   VS-HKMESDB/HKDB      8.00.760         Enterprise    SP3

 

 

select @@version

上面两个Sql 都返回了一些sql server 数据库的信息，我们看到却有两个Service Pack,这里正确的Sql server server packe 是 SP3 ,  @@version 中的Service Pack 2 是sql server 所在电脑的windows 的 service pack ,这个不能弄混了。
