ADO连接数据库字符串大全(VP,Excel,文本,Sybase,.NET等)

来源:转载

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).
