This page contains sample ADO connection strings for ODBC DSN / DSN-Less,
OLE DB Providers, Remote Data Services (RDS), MS Remote, MS DataShape.Also included are ADO.NET connection strings for each .NET Managed Provider
(SQLClient, OLEDB, and ODBC).These sample connection strings are compiled

ODBC DSN Connections
Using an ODBC DSN (Data Source Name) is a two step process. 1) You must first create the DSN via the "ODBC Data Source Administrator" program
found in your computer's Control Panel (or Administrative Tools menu in Windows 2000).
Make sure to create a SYSTEM DSN (not a USER DSN) when using ASP.
Note: You can also create the DSN via VB code.2) Then use the following connection string - with your own DSN name of course. ;-)ODBC - DSN
oConn.Open "DSN=AdvWorks;" & _
"Uid=Admin;" & _
"Pwd=;
You can also create and use a File DSN. Then use the following ADO Connection string:ODBC - File DSN
oConn.Open "FILEDSN=c:\somepath\mydb.dsn;" & _
"Uid=Admin;" & _
"Pwd=;"For more information, see: About ODBC data sources and
How to Use File DSNs and DSN-less ConnectionsNote: The problem with DSN is that Users can (and will) modify them (or delete by mistake),
then your program won't work so well... So it's better to use a DSN-Less or OLE DB Provider
connection string with a Trusted Connection if possible!
ODBC DSN-Less Connections
ODBC Driver for AS/400
oConn.Open "Driver={Client Access ODBC Driver (32-bit)};" & _
"System=myAS400;" & _
"Uid=myUsername;" & _
"Pwd=myPassword;"For more information, see: A Fast Path to AS/400 Client/Server
ODBC Driver for Access
For Standard Security:oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=c:\somepath\mydb.mdb;" & _
"Uid=Admin;" & _
"Pwd=;"If you are using a Workgroup (System database):oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=c:\somepath\mydb.mdb;" & _
"SystemDB=c:\somepath\mydb.mdw;", _
"admin", ""If MDB is located on a network share:oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _

ODBC Driver for dBASE
oConn.Open "Driver={Microsoft dBASE Driver (*.dbf)};" & _
"DriverID=277;" & _
"Dbq=c:\somepath;"Note: Specify the filename in the SQL statement. For example:
oRs.Open "Select * From user.dbf", oConn, , ,adCmdTextNote: MDAC 2.1 (or greater) requires the Borland Database Engine (BDE) to update dBase DBF files. (Q238431).For more information, see: dBASE Driver Programming Considerations

"DriverId=790;" & _
"Dbq=c:\somepath\mySpreadsheet.xls;" & _
"DefaultDir=c:\somepath;" For more information, see: Microsoft Excel Driver Programming Considerations

"ConnectString=OracleServer.world;" & _
"Uid=myUsername;" & _
"Pwd=myPassword;"For more information, see: Connection String Format and Attributes
ODBC Driver for Paradox

"Fil=Paradox 5.X;" & _
"DefaultDir=c:\dbpath\;" & _
"Dbq=c:\dbpath\;" & _
"CollatingSequence=ASCII;" Note: MDAC 2.1 (or greater) requires the Borland Database Engine (BDE) to update Paradox ISAM fDBF files. (Q230126).For more information, see: Paradox Driver Programming Considerations

oConn.Open "Provider=msdaora;" & _
"Data Source=MyOracleDB;" & _
"User Id=myUsername;" & _
"Password=myPassword;"For more information, see: Microsoft OLE DB Provider for Oracle
OLE DB Provider for Oracle (from Oracle)
For Standard Security:oConn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"User Id=myUsername;" & _
"Password=myPassword;"For a Trusted Connection:oConn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"User Id=/;" & _
"Password=;"
' OroConn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"OSAuthent=1;"
Note: "Data Source=" must be set to the appropriate Net8 name which is known to the naming method in use. For example, for Local Naming, it is the alias in the tnsnames.ora file; for Oracle Names, it is the Net8 Service Name. For more information, see: Connecting to an Oracle Database
(Note, if you get a Logon dialog, then click Cancel, then perform a one-time free signup with Oracle's TechNet system)
然后在控制面板中的odbc数据源添加系统dsn
再在oracle中配征听
最后在oracle做一下odbc连接测试
程序就可以连接了
cn.CursorDriver = rdUseOdbc
