将连接字符串中的驱动程序更改为VB.Net中的数据源

Question

I have code which has the driver in a connection string.

dim s as string = "Driver={SQL Server}; 
Server=xxx\SQLEXPRESS; 
Database=dbRegister; 

Trusted_Connection=yes"

I need to change that to:

data source=1.2.3.4;
user id=xx;
password=xxxxx;
initial catalog=xxxxx;

Connect Timeout=30"

When I just change the text, it gives this error:

    [Microsoft][ODBC Driver Manager] Data source name not found and 
                                     no default driver specified

How do I declare the datasource?

Answer 1

Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

Use serverName\\instanceName as Data Source to connect to a specific SQL Server instance.

Are you using SQL Server 2005 Express? Don't miss the server name syntax Servername\\SQLEXPRESS where you substitute Servername with the name of the computer where the SQL Server 2005 Express installation resides.

Answer 2

不要忘记您的实例名称，即Data Source=1.2.3.4\\SQLEXPRESS 。
