·         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.

通過ADO連接各種資料庫的字串翠集（中文）
http://www.topying.com/showfine.asp?id=36
在網路編程過程中，ADO（Activex Data Object）編程往往是不可少的工作，特別是開發電子商務網站。既然講到ADO資料物件，那?就順便簡單地介紹一下ADO資料物件及其功能。ADO資料物件共有七種獨立的物件，他們分別是連接物件（Connection）、記錄集物件（RecordSet）、域物件（Field）、命令物件（Command）、參數物件（Parameter）、屬性物件（Property）和錯誤物件（Error）。功能請參見附錄1。    ADO資料物件用來連接資料庫的方式有兩種，分別是ODBC和OLE DB方式，下面就分別介紹用這兩種方式連接資料庫的例子。    第一種：ODBC DSN-Less Connections    ODBC Driver for Access     ODBC Driver for dBASE     ODBC Driver for Excel     ODBC Driver for MySQL     ODBC Driver for Oracle     ODBC Driver for Paradox     ODBC Driver for SQL Server     ODBC Driver for Sybase     ODBC Driver for Sybase SQL Anywhere     ODBC Driver for Text     ODBC Driver for Teradata     ODBC Driver for Visual FoxPro    第二種：OLE DB Data Provider Connections    OLE DB Provider for Active Directory Service     OLE DB Provider for DB2     OLD DB Provider for Internet Publishing     OLE DB Provider for Index Server     OLE DB Provider for Microsoft Jet     OLE DB Provider for ODBC Databases     OLE DB Provider for Oracle (From Microsoft)     OLE DB Provider for Oracle (From Oracle)     OLE DB Provider for Simple Provider     OLE DB Provider for SQL Server    一、下面我就先講利用ODBC DSN來訪問資料庫，要完成這項工作，必須先通過“控制面板”—“管理工具”—“ODBC資料源”來建立一個資料源名，例如叫做TestData_Resoure。    1）   通過系統資料源(System DSN)的連接    <%    Dim oConn,strConn    Set oConn=Server.CreateObject(“ADODB.Connection”)    StrConn="DSN=TestData_Resoure;" & _               "Uid=AdminAccount;" & _               "Pwd=PassWord;    oConn.Open strConn    %>    2）   通過文件資料源(File DSN)的連接    <%    Dim oConn,strConn    Set oConn=Server.CreateObject(“ADODB.Connection”)    StrConn="FILEDSN=c:\somepath\mydb.dsn;" & _               "Uid=AdminAccount;" & _              "Pwd=PassWord;"    oConn.Open strConn    %>    3）   通過連接池(DSN-Less)的連接(ODBC Driver for AS/400)    <%    Dim oConn,strConn    Set oConn=Server.CreateObject(“ADODB.Connection”)    strConn= "Driver={Client Access ODBC Driver (32-bit)};" & _              "System=myAS400;" & _              "Uid=myUsername;" & _              "Pwd=myPassword;"    oConn.Open strConn    %>    二、利用資料庫驅動程式直接訪問資料庫的連接字串。    1）  ODBC Driver for Access    ●      標準的也是比較常用的連接方法    <%    Dim oConn,strConn    Set oConn=Server.CreateObject(“ADODB.Connection”)    StrConn= "Driver={Microsoft Access Driver (*.mdb)};" & _               "Dbq=”&Server.MapPath(“Testdb.mdb”);
