    •  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;"

    •  OLE DB, OleDbConnection (.NET)
       Standard Security:

    •  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;UserID=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))

    •  SqlConnection (.NET)
       Standard Security:

"Data Source=Aron1;Initial Catalog= pubs;UserId=sa;Password=asdasd;"
   - or -
"Server=Aron1;Database=pubs;UserID=sa;Password=asdasd;Trusted_Connection=False"
   (booth connection strings produces the same result)

    •  Trusted Connection:

"Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
   - or -< BR>"Server=Aron1;Database=pubs;Trusted_Connection=True;"
   (booth connection strings produces the same result)

(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()

         How to define wich network protocol to use
        Example:
        "Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog= pubs;UserID=sa;Password=asdasd;"

Name

Network library

dbnmpntw

Win32 Named Pipes

dbmssocn

Win32 Winsock TCP/IP

dbmsspxn

Win32 SPX/IPX

dbmsvinn

Win32 Banyan Vines

dbmsrpcn

Win32 Multi-Protocol (Windows RPC)

      • Important note!
        When connecting through the SQLOLEDB provider use the syntax Network Library=dbmssocn
        and when connecting through MSDASQL provider use the syntax Network=dbmssocn

      •  All SqlConnection connectionstring properties
        This table shows all connectionstring properties for the ADO.NET SqlConnection object. Most of the properties are also used in ADO. All properties and descriptions is from msdn.

Name

Default

Description

Application Name

 

The name of the application, or '.Net SqlClient Data Provider' if no application name is provided.

AttachDBFilename
-or-
extended properties
-or-
Initial File Name

 

The name of the primary file, including the full path name, of an attachable database. The database name must be specified with the keyword 'database'.

Connect Timeout
-or-
Connection Timeout

15

The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.

Connection Lifetime

0

When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Useful in clustered configurations to force load balancing between a running server and a server just brought on-line.

Connection Reset

'true'

Current Language

 

The SQL Server Language record name.

-or-
Server
-or-
Address
-or-
Addr
-or-
Network Address

Network Library
-or-
Net

'dbmssocn'

The network library used to establish a connection to an instance of SQL Server. Supported values include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsipcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (TCP/IP).
The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, "." or "(local)"), shared memory is used.

Size in bytes of the network packets used to communicate with an instance of SQL Server.

Password
-or-
Pwd

 

The password for the SQL Server account logging on.

Persist Security Info

When true, the SQLConnection object is drawn from the appropriate pool, or if necessary, is created and added to the appropriate pool.

User ID

 

The SQL Server login account.

Workstation ID

the local computer name

The name of the workstation connecting to SQL Server.

      • Note
        Use ; to separate each property.
        If a name occurs more than once, the value from the last one in the connectionstring will be used.
        If you are building your connectionstring in your app using values from user input fields, make sure the user can't change the connectionstring by inserting an additional property with another value within the user value.
