方法不是很好...还要花时间去装vb

我只有一种万能而且万无一失的连接方式，access,sql通吃，实际上我根本记不住连接语句，但我从不失手，我经常来这里推销这个办法，有人会看到很多次了，谁让总有人问呢？有一个办法保证你万无一失，你用vb的ado控件连接该库，（不用写任何代码！也不用设置dns）在vb里右键点击ado控件，在创建里连接一个库，然后检测连接成功就会自动生成正确的sql连接语句，拷贝出来用就可以了。我的qq号28963147。哈哈，我又推销了一次，万能狗皮膏药！！独家专利！！

ADO连接数据库字符串大全（VP,Excel,文本,Sybase,.NET等)
发布于：2000-1-1
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
by Carl Prothman, a Microsoft Visual Basic MVP
Enjoy!

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 Connections

Note: 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)};" & _
　　　　　　　　　 "Dbq=\\myServer\myShare\myPath\myDb.mdb;"

For more information, see: Microsoft Access Driver Programming Considerations

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, , ,adCmdText

Note: 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

ODBC Driver for Excel
　
oConn.Open "Driver={Microsoft Excel Driver (*.xls)};" & _
　　　　　　　　　 "DriverId=790;" & _
　　　　　　　　　 "Dbq=c:\somepath\mySpreadsheet.xls;" & _
　　　　　　　　　 "DefaultDir=c:\somepath;"

For more information, see: Microsoft Excel Driver Programming Considerations

ODBC Driver for MySQL (via MyODBC)
　
To connect to a local database

oConn.Open "Driver={mySQL};" & _
　　　　　　　　　 "Server=MyServerName;" & _
　　　　　　　　　 "Option=16834;" & _
　　　　　　　　　 "Database=mydb;"

To connect to a remote database

oConn.Open "Driver={mySQL};" & _
　　　　　　　　　 "Server=db1.database.com;" & _
　　　　　　　　　 "Port=3306;" & _
　　　　　　　　　 "Option=131072;" & _
　　　　　　　　　 "Stmt=;" & _
　　　　　　　　　 "Database=mydb;" & _
　　　　　　　　　 "Uid=myUsername;" & _
　　　　　　　　　 "Pwd=myPassword;"

For more information, see: Programs Known to Work with MyODBC

ODBC Driver for Oracle
　
For the current Oracle ODBC Driver from Microsoft:

oConn.Open "Driver={Microsoft ODBC for Oracle};" & _
　　　　　　　　　 "Server=OracleServer.world;" & _
　　　　　　　　　 "Uid=myUsername;" & _
　　　　　　　　　 "Pwd=myPassword;"

For the older Oracle ODBC Driver from Microsoft:

oConn.Open "Driver={Microsoft ODBC Driver for Oracle};" & _
　　　　　　　　　 "ConnectString=OracleServer.world;" & _
　　　　　　　　　 "Uid=myUsername;" & _
　　　　　　　　　 "Pwd=myPassword;"

For more information, see: Connection String Format and Attributes

ODBC Driver for Paradox
　
oConn.Open "Driver={Microsoft Paradox Driver (*.db)};" & _
　　　　　　　　　 "DriverID=538;" & _
　　　　　　　　　 "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
