ADO连接数据库字符串大全 



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 



ODBC Driver for SQL Server 
　 
For Standard Security: 

oConn.Open "Driver={SQL Server};" & _ 
　　　 　　　　　 "Server=MyServerName;" & _ 
　　　　　　　　 "Database=myDatabaseName;" & _ 
　　　　　　　　 "Uid=myUsername;" & _ 
　　 　　　　　　 "Pwd=myPassword;" 

For Trusted Connection security: 

oConn.Open "Driver={SQL Server};" & _ 
　　　 　　　　　 "Server=MyServerName;" & _ 
　　　　　　　　　 "Database=myDatabaseName;" & _ 
　　　　　　　　　 "Uid=;" & _ 
　　 　　　　　　 "Pwd=;" 

' or 

oConn.Open "Driver={SQL Server};" & _ 
　　　 　　　　　 "Server=MyServerName;" & _ 
　　　　　　　　　 "Database=myDatabaseName;" & _ 
　　　　　　　　　 "Trusted_Connection=yes;" 

To Prompt user for username and password 

oConn.Properties("Prompt") = adPromptAlways 
oConn.Open "Driver={SQL Server};" & _ 
　　　 　　　　　 "Server=MyServerName;" & _ 
　　　 　　　　　 "DataBase=myDatabaseName;" 
　　 

For more information, see: SQLDriverConnect (ODBC) 



ODBC Driver for Sybase 
　 
If using the Sybase System 11 ODBC Driver: 

oConn.Open "Driver={SYBASE SYSTEM 11};" & _ 
　　　　　　　　　 "Srvr=myServerName;" & _ 
　　　　　　　　 "Uid=myUsername;" & _ 
　　 　　　　　　 "Pwd=myPassword;" 

If using the Intersolv 3.10 Sybase ODBC Driver: 

oConn.Open "Driver={INTERSOLV 3.10 32-BIT Sybase};" & _ 
　　　　　　　　　 "Srvr=myServerName;" & _ 
　　　　　　　　 "Uid=myUsername;" & _ 
　　 　　　　　　 "Pwd=myPassword;" 

For more information, see: Sybase System 10 ODBC Driver Reference Guide 



ODBC Driver for Sybase SQL Anywhere 
　 
oConn.Open "ODBC; Driver=Sybase SQL Anywhere 5.0;" & _ 
　　　　　　　　　 "DefaultDir=c:\dbpath\;" & _ 
　　　　　　　　　 "Dbf=c:\sqlany50\mydb.db;" & _ 
　　　　　　　　 "Uid=myUsername;" & _ 
　　 　　　　　　 "Pwd=myPassword;" 
　　　　　　　　　 "Dsn="""";" 

Note: Including the DSN tag with a null string is absolutely critical or else you get the dreaded -7778 error.
