Database Connect String
 

Microsoft Access Connect Database


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;", _
           "myUsername", "myPassword"

If want to open up the MDB exclusively

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=c:\somepath\mydb.mdb;" & _
           "Exclusive=1;" & _
           "Uid=admin;" & _
           "Pwd=" 

If MDB is located on a Network Share

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=\\myServer\myShare\myPath\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="

If MDB is located on a remote machine

- Or use an XML Web Service via SOAP Toolkit or ASP.NET
- Or upgrade to SQL Server and use an IP connection string
- Or use an ADO URL with a remote ASP web page
- Or use a
MS Remote or RDS connection string
  

If you don't know the path to the MDB (using ASP)

<%  ' ASP server-side code
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=" & Server.MapPath(".") & "\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="
%>

This assumes the MDB is in the same directory where the ASP page is running. Also make sure this directory has Write permissions for the user account.
 

If you don't know the path to the MDB (using VB)

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
           "Dbq=" & App.Path & "\myDb.mdb;" & _
           "Uid=admin;" & _
           "Pwd="

This assumes the MDB is in the same directory where the application is running.


ODBC Driver for AS/400 (from IBM)

oConn.Open "Driver={Client Access ODBC Driver (32-bit)};" & _
           "System=myAS400;" & _

           "Pwd=myPassword"

For more information, see:   A Fast Path to AS/400 Client/Server


ODBC Driver for dBASE

oConn.Open "Driver={Microsoft dBASE Driver (*.dbf)};" & _

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).

ODBC Driver for SQL Server


For Standard Security

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

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

To Prompt user for username and password

           "DataBase=myDatabaseName"

To connect to SQL Server running on the same computer

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

To connect to SQL Server running on a remote computer (via an IP address)

oConn.Open "Driver={SQL Server};" & _
           "Server=xxx.xxx.xxx.xxx;" & _
           "Address=xxx.xxx.xxx.xxx,1433;" & _

           "Database=myDatabaseName;" & _
           "Uid=myUsername;" & _
           "Pwd=myPassword"

Where:
- xxx.xxx.xxx.xxx is an IP address
- 1433 is the default port number for SQL Server.
