SQLSERVER一些公用DLL的作用解释

如果你的SQLSERVER安装在C盘的话,下面的路径就是相应SQLSERVER版本的公用DLL的存放路径

SQL2005

C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies\

SQL2008

C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies\

SQL2012

C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies\

可以看到随着SQLSERVER版本的升级,这些公用DLL变得越来越多了,因为SQLSERVER的功能越来越多了


这些DLL有什么用??

这些DLL是供SQLSERVER调用的,因为这些公用DLL在SQLSERVER的很多组件中都有用到,所以SQLSERVER就把这些

DLL放到X:\Program Files\Microsoft SQL Server\X\SDK\Assemblies\文件夹下以供其他SQLSERVER组件调用

例如SSIS、SSAS、数据库引擎还有其他的工具

其实从文件夹路径名我们就可以知道这些DLL的作用:SDK\Assemblies\

大家不知道SDK的含义可以百度一下,不过可能大家比较赖,我就贴出来吧

SDK(Software Development Kit, 即软件开发工具包 )一般是一些被软件工程师用于为特定的软件包、软件框架、硬件平台、操作系统等

建立应用软件的开发工具的集合。

资深程序员一定知道SDK的作用,他就是某个软件提供给我们程序员用来开发的一些接口或者API

本人觉得X:\Program Files\Microsoft SQL Server\X\SDK\Assemblies\文件夹下面的这些DLL不只是提供给SQLSERVER调用的

我们也可以调用这些DLL来开发SQLSERVER数据库的一些相关软件和工具

例子一:

园子里的胡勇大侠就用了下面的两个DLL来做出了: (喷血分享)利用.NET生成数据库表的创建脚本,类似SqlServer编写表的CREATE语句

Microsoft.SqlServer.ConnectionInfo.dll

Microsoft.SqlServer.Management.Sdk.Sfc.dll

例子二:

又例如这个帖子:用c#做了个,sqlServer2005里面那个事件监控器一样的程序,启动问题请帮看看

用Microsoft.SqlServer.ConnectionInfo.dll这个DLL做一个类似于SQL TRACE的工具出来,用来实时查看执行的脚本以及其他信息

例子三:

SQLDoc Sharp(SQLSERVER数据库文档生成工具)

这个工具在codeproject上可以下载:http://www.codeproject.com/Articles/35790/SQLDoc-Sharp

用到了下面的DLL

Microsoft.SqlServer.ConnectionInfo.dll

Microsoft.SqlServer.Management.Sdk.Sfc.dll

Microsoft.SqlServer.Smo.dll

Microsoft.SqlServer.SmoExtended.dll

Microsoft.SqlServer.SqlEnum.dll


公用DLL用什么语言编写?

我们可以发现上面的三个例子中的工具都是用.NET编写的工具,包括SQLDoc Sharp都是用.NET编写的winfrom软件

我们用ILSpy这个软件反编译一下各个SQLSERVER版本的下DLL

将DLL全部拖入去ILSpy里面

SQL2005

SQL2008

SQL2012

SQL2008里面有两个DLL是不能够反编译的,分别是Redist_TSqlLanguageService.dllRedist_DACFramework.dll

SQL2012里面只有一个DLL是不能够反编译的,是Redist_TSqlLanguageService.dll

不能被反编译的DLL有可能是用C或者C++编写的

我估计这些不能反编译的dll不会提供API功能给用户,只是给SQLSERVER调用的,而且这些DLL对于SQLSERVER的性能有至关重要的作用

所以用C或者C++编写

从上面反编译这些DLL的情况来看,SQLSERVER里面有很大一部分组件或者代码都是用.NET来编写的

除了一些关键功能或者涉及到性能相关的功能组件用C或者C++编写

这里从另一个侧面也可以看出微软对.NET的重用,从SQLSERVER2005开始大量用.NET来编写一些组件代码

从上面三个例子中也可以看出为什麽他们首选.NET来编写这些工具,因为这些公用DLL本来就是.NET DLL(可托管代码)


简单介绍DLL

限于本人的能力有限,本人就只简单介绍比较熟悉的DLL,其他不熟悉的大家可以查MSDN或者百度

我这里会给出一些DLL的资料和查百度、MSDN时候的结果

我这里只介绍SQLSERVER2012的,因为SQLSERVER2012比较齐全,但是某些功能在不同的SQLSERVER版本里会有变化

例如上面第二个例子里:用c#做了个,sqlServer2005里面那个事件监控器一样的程序,启动问题请帮看看

里面说到了TMO这个类在SQL2005版本的SDK里面和SQL2008版本的SDK里面有变化,导致运行时出错

使用Trace Management Object监测和诊断SQL Server(一)

在SQL Server 2005里TMO对象被实现在了Microsoft.SqlServer.ConnectionInfo.dll里,

在SQL Server 2008里TMO对象则被移到了Microsoft.SqlServer.ConnectionInfoExtended.dll里,

但仍然在Microsoft.SqlServer.Management.Trace命名空间里。

类似上面的有变化的API我就不说了,大家开发的时候一定要查清楚MSDN和百度,不要搞错,因为这些SDK的文档比较少

大部分都是E文的,开发起来会比较头痛

Microsoft.SqlServer.SmoExtended.DLL

Microsoft.SqlServer.Management.Sdk.Sfc.DLL

Microsoft.SqlServer.ConnectionInfo.DLL

Microsoft.SqlServer.ConnectionInfoExtended.DLL

SMO:SQLSERVER管理对象

监控SQLSERVER或者连接SQLSERVER用到

提供SMO对象功能,是SqlServer Management Ojbects的简称,由SQL2005提供的管理对象

只要SQL Server Management Studio能实现的东西,用smo都能实现,因为SQL Server Management Studio就是用smo开发的。

如果你有足够的实力,完全可以开发一个可以藐视SQL Server Management Studio的工具,比如加入智能感知的功能

为了支持 SQL Server 的管理,Integration Services 提供了可以遍历 SQL 管理对象 (SMO) 的对象的枚举器。

例如,包可使用 SMO 枚举器对某个 SQL Server 安装中的 Jobs 集合中的每个作业执行相同的管理功能。
