连接SQL Server 1:ODBC Standard Security: "Driver={SQL Server};Server=Aron1;Database=pubs;Uid=sa;Pwd=asdasd;"
Trusted connection: "Driver={SQL Server};Server=Aron1;Database=pubs;Trusted_Connection=yes;"
Prompt for username and password: oConn.Properties("Prompt") = adPromptAlways oConn.Open "Driver={SQL Server};Server=Aron1;DataBase=pubs;" 2:OLE DB, OleDbConnection (.NET) Standard Security: "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
Trusted Connection: "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;" (use serverName/instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
Prompt for username and password: oConn.Provider = "sqloledb" oConn.Properties("Prompt") = adPromptAlways oConn.Open "Data Source=Aron1;Initial Catalog=pubs;"
Connect via an IP address: "Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;" (DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))
3:SqlConnection (.NET) Standard Security: "Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;" - or - "Server=Aron1;Database=pubs;User ID=sa;Password=asdasd;Trusted_Connection=False" (both connection strings produces the same result)
Trusted Connection: "Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;" - or - "Server=Aron1;Database=pubs;Trusted_Connection=True;" (both connection strings produces the same result)
(use serverName/instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000) Connect via an IP address: "Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;" (DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default)) Declare the SqlConnection:
C#: using System.Data.SqlClient; SqlConnection oSQLConn = new SqlConnection(); oSQLConn.ConnectionString="my connectionstring"; oSQLConn.Open();
VB.NET: Imports System.Data.SqlClient Dim oSQLConn As SqlConnection = New SqlConnection() oSQLConn.ConnectionString="my connectionstring" oSQLConn.Open()
