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. You can also create the DSN via Visual Basic code.
2) Then use the following connection string - with your own DSN
name of course.
ODBC - DSN
oConn.Open "DSN=mySystemDSN;" & _
"Uid=myUsername;" & _
"Pwd=myPassword"
ODBC - File DSN
oConn.Open "FILEDSN=c:\somepath\mydb.dsn;" & _
"Uid=myUsername;" & _
"Pwd=myPassword"
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 or delete them 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 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;", _
"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.

OLE DB Provider for Simple Provider
The Microsoft OLE DB Simple Provider (OSP) allows ADO to access any data for which a provider has been written using the OLE DB Simple Provider Toolkit. Simple providers are intended to access data sources that require only fundamental OLE DB support, such as in-memory arrays or XML documents.
OSP in MDAC 2.6 has been enhanced to support opening hierarchical ADO Recordsets over arbitrary XML files. These XML files may contain the ADO XML persistence schema, but it is not required. This has been implemented by connecting the OSP to the MSXML2.DLL, therefore MSXML2.DLL or newer is required.
oConn.Open "Provider=MSDAOSP;" & _
"Data Source=MSXML2.DSOControl.2.6"
oRS.Open "http://WebServer/VirtualRoot/MyXMLFile.xml",oConn

Remote Data Service (RDS) Connections
The following examples show how to connect to a remote database using the RDS Data Control. When using the RDS DataControl's Server/Connect / SQL properties, the RDS DataControl uses the RDS DataFactory on the remote server. If you use the RDS DataControl's URL property, then the RDS DataFactory is not used at all.
WARNING: The RDS DataFactory can be a major security hole if not setup and configured correctly! For more information, see RDS FAQ #24
WARNING: RDS is considered obsolete by Microsoft
RDS DataControl - Connect Property
With the RDS default handler disabled
With oRdc
.Server = "http://myServerName"
.Sql = "Select * From Authors Where State = 'CA'"
.Connect = "Provider=sqloledb;" & _
"Data Source=(local);" & _
"Initial Catalog=pubs;" & _
"User Id=myUsername;" & _
"Password=myPassword"
.Refresh
End With
With the RDS default handler enabled
With oRdc
.Server = "http://myServerName"
.Handler = "MSDFMAP.Handler"
.Connect = "Data Source=MyConnectTag;"
.Sql = "MySQLTag(""CA"")"
.Refresh
End With
The corresponding CONNECT and SQL sections in the default handler \WINNT\MSDFMAP.INI file would be:
[connect MyConnectTag]
Access = ReadWrite
Connect = "Provider=sqloledb;
Data Source=(local);
Initial Catalog=pubs;
User Id=sa;
Password=" (put all of this on single line!)
[sql MySQLTag]

.NET Data Provider Connections
SQL Server .NET Data Provider (System.Data.SqlClient)
The SQL Server .NET Data Provide allows you to connect to a Microsoft SQL Server 7.0 or 2000 databases.
For Microsoft SQL Server 6.5 or earlier, use the OLE DB .NET Data Provider with the "SQL Server OLE DB Provider" (SQLOLEDB).
Note: The SQL Server .NET Data Provider knows which Provider it is. Hence the "provider=" part of the connection string is not needed.
Using C#:
using System.Data.SqlClient;
...
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString = "Data Source=(local);" +
"Initial Catalog=mySQLServerDBName;" +
"Integrated Security=yes";
oSQLConn.Open();
Using VB.NET:
Imports System.Data.SqlClient
...
Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString = "Data Source=(local);" & _
"Initial Catalog=mySQLServerDBName;" & _
"Integrated Security=yes"
oSQLConn.Open()
If connection to a remote server (via IP address):
oSQLConn.ConnectionString = "Network Library=DBMSSOCN;" & _
"Data Source=xxx.xxx.xxx.xxx,1433;" & _
"Initial Catalog=mySQLServerDBName;" & _
"User ID=myUsername;" & _
"Password=myPassword"
Where:
- "Network Library=DBMSSOCN" tells SqlConnection to use TCP/IP Q238949
- xxx.xxx.xxx.xxx is an IP address.
- 1433 is the default port number for SQL Server. Q269882 and Q287932
- You can also add "Encrypt=yes" for encryption
