这些连接字符串之间的区别？ [英] Difference between these connection strings?
问题描述
谁能告诉我以下连接字符串之间的有效区别：
Can anybody tell me the effective difference between the following connection strings:
<add key="ConnectionString" value="server=tcp:192.168.0.12\Sqlserver2005;database=;user id=sa;password=;">
<add key="ConnectionString" value="server=192.168.0.12\Sqlserver2005;database=;user id=sa;password=;Network Library=DBMSSOCN;">
我相信两者实际上是相同的。指定 Network Library = DBMSSOCN使用TCPIP显式连接，并在服务器值前加上TCP做同样的事情。
I believe both are effectively the same. Specifying "Network Library=DBMSSOCN" explicitly connects using TCPIP and prefixing server value with TCP does the same thing.
请告诉我是否有任何区别或对性能的影响
Please tell me if there is any difference or any performance implication of specifying these settings in web.config.
推荐答案
这两个选项之间的区别是：
The difference between the two options is:
指定协议
通过使用
多协议= rpc
共享内存= lpc
NWlink IPX / SPX = spx
NWlink IPX / SPX = spx
印度榕树=葡萄藤
Apple Talk = adsp
Apple Talk = adsp
TCP = tcp
TCP = tcp
这是推荐的方式。我也感到它更安全，因为DLL名称比协议名称更容易更改。
This is the recommended way. I also feel its safer as DLL names are likelier to change than protocol names.
它还允许您更改端口号，而不是通过使用全面配置它SQL Server客户端网络实用程序。
It also allows you to change the port number, rather than configuring it across the board by using the SQL Server Client Network Utility.
在没有 dll 扩展名的情况下指定库
Specyfying the Library without the dll extension
指定该库将使用与不带.dll扩展名的实际网络DLL库文件相同的名称。
Specifying the library will use the same name as the actual network DLL library file without the .dll extension.
示例：
TCP / IP：C：\WINDOWS\system32\DBMSSOCN.dll
TCP/IP: C:\WINDOWS\system32\DBMSSOCN.dll
命名管道：C：\ WINDOWS\system32\DBNMPNTW.dll
Named Pipes: C:\WINDOWS\system32\DBNMPNTW.dll
多协议（RPC）：C：\WINDOWS\system32\DBMSRPCN.dll
Multiprotocol (RPC): C:\WINDOWS\system32\DBMSRPCN.dll
NWLink IPX / SPX：C：\WINDOWS\system32\DBMSSPXN.dll
NWLink IPX/SPX: C:\WINDOWS\system32\DBMSSPXN.dll
AppleTalk：C：\WINDOWS\system32 MSDBMSADSN.dll
AppleTalk: C:\WINDOWS\system32\DBMSADSN.dll
印度榕树：C：\WINDOWS\system32\DBMSVINN.dll
Banyan VINES: C:\WINDOWS\system32\DBMSVINN.dll
当您要编写自己的网络时，这将最有效ork库。
请参阅SQL Server客户端网络实用程序。
This will work best when you want to write your own network library. Please see SQL Server Client Network Utility.
性能的平衡是微小的，并不引人注目。最好遵循标准并在web.config中进行配置，因为其他开发人员将知道在哪里查找连接设置。类似于在Java中建立数据源连接。
The performance trade-off is minute and not noticeable. It is best to stick to standards and have it configured in the web.config as other developers will know where to look for the connections settings. Similar to having a data-source connection in java.
