oConn.Open “Driver={SQL Server};Server=Aron1;DataBase=pubs;”

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;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)

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’ Determines whether the database connection is reset when being removed from the pool. Setting to ‘false’ avoids making an additional server round-trip when obtaining a connection, but the programmer must be aware that the connection state is not being reset.
Current Language The SQL Server Language record name.
Data Source
-or-
Server
-or-
Address
-or-
Addr
-or-
Network Address The name or network address of the instance of SQL Server to which to connect.
Enlist ‘true’ When true, the pooler automatically enlists the connection in the creation thread’s current transaction context.
Initial Catalog
-or-
Database The name of the database.
Integrated Security
-or-
Trusted_Connection ‘false’ Whether the connection is to be a secure connection or not. Recognized values are ‘true’, ‘false’, and ’sspi’, which is equivalent to ‘true’.
Max Pool Size 100 The maximum number of connections allowed in the pool.
Min Pool Size 0 The minimum number of connections allowed in the pool.
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.
Packet Size 8192 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 ‘false’ When set to ‘false’, security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state. Resetting the connection string resets all connection string values including the password.
Pooling ‘true’ 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.

ACE OLEDB 12.0

标准安全策略
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:/myFolder/myAccess2007file.accdb;Persist Security Info=False;

使用了密码的数据库
如果您的Access 2007数据库设置了密码，您需要特别的在连接字符串中指定它。
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:/myFolder/myAccess2007file.accdb;Jet OLEDB:Database Password=MyDbPassword;

ODBC

标准
Driver={Microsoft Excel Driver (*.xls)};DriverId=790;Dbq=C:/MyExcel.xls;DefaultDir=c:/mypath;

SQL表达式"SELECT * FROM [sheet1$]"。例如：在excel工作表名称后面跟"$"字符并且使用"[" "]"将其括起来。

OLE DB

标准
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:/MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";

"HDR=Yes;" 表示工作表的第一行是表头，没有数据。 "HDR=No;"与之相反。
"IMEX=1;"告诉驱动程序始终将"intermixed"数据类型(numbers, dates, strings等等)作为文本型读取。
注意：该选项可能引起Excel工作表写权限的修改。

ACE OLEDB 12.0

标准
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:/myFolder/myExcel2007file.xlsx;Extended Properties="Excel 12.0;HDR=YES";

"HDR=Yes;" 表示工作表的第一行是表头，没有数据。 "HDR=No;"与之相反。

如果您使用的是 2.x DBF，您不必使用dBase或者Jet driver，使用"Visual FoxPro / FoxPro 2.x"替换VFP driver。Visual FoxPro ODBC和OLEDB驱动可以用于所有的Foxpro数据表，其中包括很老的foxbase数据表以及dBaseII, dBaseIII, Clipper文件等。
ODBC

标准
Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;Dbq=c:/mydbpath;
