[英]Connecting to SQL server via TCP/IP, not NP
As I found out, my SQL server has disabled Named Pipes, but enabled TCP/IP (and it will stay this way). 我发现,我的SQL服务器已禁用命名管道,但启用了TCP / IP(它将保持这种方式)。 Now I am trying to connect from the visual studio to the database, but with no luck. 现在我正在尝试从visual studio连接到数据库,但没有运气。 I've tried so far: 我到目前为止尝试过:
string connstring = "Data Source=192.168.1.1:1433 ;Initial Catalog=np-sparcsn4-custom;Persist Security Info=True;User ID=xxxx;Password=/*****/";
string connstring = "Data Source=192.168.1.1:1433 ; Network Library=DBMSSOCN; Initial Catalog=np-sparcsn4-custom;Persist Security Info=True;User ID=xxxx;Password=/*****/";
I've tried to replace the IP address with name - no luck. 我试图用名字替换IP地址 - 没有运气。 When I try to connect using the table adapter I can preview the data, same if I'd use ie grid - but in the code I simply can't open connection to it: I always have Network related or server specific error, usually its either 当我尝试使用表适配器连接时,我可以预览数据,如果我使用ie网格也一样 - 但在代码中我根本无法打开它的连接:我总是有网络相关或服务器特定的错误,通常是或
Named Pipes Provider: Could not open a connection to SQL Server [5]
or 要么

Update: 更新:
I've tried 我试过了
string connstring = "Server=tcp:192.168.1.1,1433 ;Initial Catalog=np-sparcsn4-custom;Persist Security Info=True;User ID=xxx;Password=/****/";
or 要么
"Server=tcp:ponln4report,1433 ....
and I've got error: 我有错误:
provider: TCP Provider, error: 0 - A non-recoverable error occurred during a database lookup**strong text**
EDI2: I've found an older SQL server 2005 that I can connect without a problem. EDI2:我发现了一个旧的SQL Server 2005,我可以毫无问题地连接。 It is a bit of a pain because it lacks ie Date and Time data types, but I guess it has to do for now. 这有点痛苦,因为它缺少日期和时间数据类型,但我想它现在必须做。
For C#, use this connection string 对于C#,请使用此连接字符串
connectionString="Data Source=192.168.1.1,1433;Initial Catalog=np-sparcsn4-custom;Integrated Security=false;User ID=your_username;Password=your_password"
If you need to modify a web.config file, add this node: 如果需要修改web.config文件,请添加以下节点:
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=192.168.1.1,1433;Initial Catalog=np-sparcsn4-custom;Integrated Security=false;User ID=your_username;Password=your_password" providerName="System.Data.SqlClient" />
</connectionStrings>
