（轉）各種數據庫的連接串(總結DSN的使用方法)

1.Oracle
    標準連接（Standard Security）:
    "Provider=msdaora;Data Source=MyOracleDB;User Id=UserName;Password=asdasd;"
    這是Microsoft的格式, 下面是Oracle的格式（提供者不同）
    "Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=Username;Password=asdasd;"
    注意："Data Source=" 必須根據相應的命名方法設置爲Net8名稱。例如對於局部命名，它是tnsnames.ora中的別名，對於Oracle命    名，它是Net8網絡服務名。
    信任連接（Trusted Connection）:
    "Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;"
    或者設置user ID爲 "/"
    "Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=/;Password=;"
    2.SQL Server
    標準連接（Standard Security）:
    "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
    信任連接（Trusted connection）:
    "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
    (如果連接一個具體的已命名SQLServer實例,使用Data Source=Servere Name/Instance Name;但僅適用於 SQLServer2000)例    如："Provider=sqloledb;Data Source=MyServerName/MyInstanceName;Initial Catalog=MyDatabaseName;User     Id=MyUsername;Password=MyPassword;"
    連接時彈出輸入用戶名和口令對話框:
    Conn.Provider = "sqloledb"
    Conn.Properties("Prompt") = adPromptAlways
    Conn.Open "Data Source=Aron1;Initial Catalog=pubs;"
    通過IP地址連接:
    "Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;UserID=sa;Password=asdasd;"
    (DBMSSOCN=TCP/IP代替Named Pipes, Data Source的末尾是需要使用的端口號(缺省爲1433))
    3.Access
    標準連接（Standard Security）:
    "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=/somepath/mydb.mdb;User Id=admin;Password=;"
    組連接（系統數據庫）
     "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=/somepath/mydb.mdb;Jet OLEDB:System Database=system.mdw;","admin", ""
    帶口令的連接:
    "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=/somepath/mydb.mdb;Jet OLEDB:Database Password=MyDbPassword;","admin", ""
    4.MySQL
    標準連接:
    "Provider=MySQLProv;Data Source=mydb;User Id=UserName;Password=asdasd;"
    Data Source是MySQL數據庫的名字，也可以使用server=localhost;DB=test

    5.DB2
    OLE DB, OleDbConnection (.NET) from ms
    TCP/IP:
    "Provider=DB2OLEDB;Network Transport Library=TCPIP;Network Address=XXX.XXX.XXX.XXX;Initial Catalog=MyCtlg;Package     Collection=MyPkgCol;Default Schema=Schema;User ID=MyUser;Password=MyPW"
    APPC:
    "Provider=DB2OLEDB;APPC Local LU Alias=MyAlias;APPC Remote LU Alias=MyRemote;Initial Catalog=MyCtlg;Package     Collection=MyPkgCol;Default Schema=Schema;User ID=MyUser;Password=MyPW"
    AS400
    "Provider=IBMDA400;Data source=myAS400;User Id=myUsername;Password=myPassword;"
    6.Excel

第一種 - 這種方法用在ACCESS中最多
strconn = "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" & Server.MapPath("aspfree.mdb")
set conn = server.createobject("adodb.connection")
conn.open strconn

第二種－這種方法用在SQL SERVER中多
strconn = "Driver={SQL Server};Description=sqldemo;SERVER=127.0.0.1;UID=LoginID;PWD=Password;DATABASE=Database_Name
set conn = server.createobject("adodb.connection")
conn.open strconn

第三種
strconn="Driver={MicrosoftAccessDriver(*.mdb)};DBQ=F:/Inetpub/wwwroot/somedir/db1.mdb;DefaultDir=f:/Inetpub/wwwroot/somedir;uid=LoginID;pwd=Password;DriverId=25;FIL=MSAccess;" set conn = server.createobject("adodb.connection")
conn.open strconn

第四種運用系統數據源
The following uses a Data Source Name:

set conn = server.createobject("adodb.connection")
conn.open "Example"
'This is created in the Control Panel using the 32 bit ODBC Driver. If you don't know how to setup here is a perfect example on ActiveServerPages.com (click here to find how to create System and File DSN's!

第五種運用ODBC數據源，前提是你必須在控制面板的ODBC中設置數據源
set rs = server.createobject("adodb.recordset")
rs.open "tblname", "DSNName", 3, 3
