how to config db connection in a DSN-less server

congfuzi · #1 (**permalink**) January 14th, 2005, 06:19 PM

I used DW MX2004 to created couple of form collection info and info display ASP pages, with an Access db. DW auto generated connection file as always. It worked fine in my local. When I upload to 1and1 host server, I found out they can't add DSN to ODBC. Instead, they give following code as connection samples:

<%
Set OBJdbConnection = Server.CreateObject("ADODB.Connection")
OBJdbConnection.Open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.Mappath("../db/products.mdb") & ";"
SQLQuery = "SELECT * FROM PRODUCTS"
Set RS = OBJdbConnection.Execute(SQLQuery)
%>

In DW, code for connection is

Set OBJdbConnection = Server.CreateObject("ADODB.Recordset")
OBJdbConnection.ActiveConnection = MM_dsnname_STRING

And that MM_dsnname_STRING is calling a dsn set in ODBC.

Since I've already have these pages done, I try to avoid to redo the codes. Is there anyway to define "MM_dsnname_STRING" with the connection sample 1and1 gives?

appreciate for any help!

Sure, you can. Right now, MM_dsnname_STRING is filled with a reference to the DSN. All you need to do is replace it with a proper connection string.

The one your ISP gave is very old and *not* recommended. Try this instead in your connection file:

MM_dsnname_STRING = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
   "Data Source=" & Server.Mappath("../db/products.mdb") & ";" & _
   "User Id=admin;" & _
   "Password="

Then your code can stay the same:

OBJdbConnection.ActiveConnection = MM_dsnname_STRING

Instead of accepting a DSN name, and doing a lookup for the database info, the connection now gets a proper OleDb connection directly.

Make sure you adjust the path in Server.MapPath tp match the path you're calling this code from.

Cheers,

The power of a Google search.

Thanks for the connection string.

Using it I got my database on 1and1 working with my Dreamweaver .asp pages

Now the only issue is in Dreamweaver my local and remote connection pages differ. I guess in the future I could sim the 1and1 dir structure on my local IIS server so the connection string will be the same.

Thanks again:)

Yeah, you could do that.

Alternatively, you can store the connection string in the global.asa file and never overwrite that file when you update the site.

Or you can Server.MapPath as I suggested in an earlier post. Server.MapPath takes a virtual path and maps it to a physical path. So, Server.MapPath("Databases") could be c:\yoursite\Databases on your local system and something like D:\webs\customers\YourCompany\YourSite\Databases on the production server.

Hey Guys,

I am having a similar problem and attempted to follow this post but I was unsuccessful.

I have a local site developed in ASP with an access database which is working fine however when I uploaded it to 1and1 I realized that I should of left development to the pro's =(

I have the following script in my connection file generated in Dreamweaver MX:

<%
// FileName="Connection_odbc_conn_dsn.htm"
// Type="ADO"
// DesigntimeType="ADO"
// HTTP="false"
// Catalog=""
// Schema=""
var MM_user_logins_STRING = "dsn=user_logins;"
%>

1and1 provides the following example script.

<html>
<title>Database query using ASP</title>
<body bgcolor="FFFFFF">
<h2>Query table <b>Products</b> with ASP</h2>
<%
Set dbaseConn = Server.CreateObject("ADODB.Connection")
dbaseConn.Open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.Mappath("\db\products.mdb") & ";"
SQLQuery = "SELECT * FROM PRODUCTS"
Set RS = dbaseConn.Execute(SQLQuery)
%>
<%
Do While Not RS.EOF
%>
<%=RS("name")%>, <%=RS("description")%>, <%=RS("price")%> DM
<p>
<%
RS.MoveNext
Loop
RS.Close
Set RS = Nothing
dbaseConn.Close
Set dbaseConn = Nothing
%>
</body>
</html>

http://faq.1and1.com/scripting_langu...atabase/2.html

I am a little bit lost and attempted the following script:

<%
// FileName="Connection_odbc_conn_dsn.htm"
// Type="ADO"
// DesigntimeType="ADO"
// HTTP="false"
// Catalog=""
// Schema=""
var MM_user_logins_STRING = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
   "Data Source=" & Server.Mappath("../db/mydb.mdb") & ";" & _
   "User Id=admin;" & _
   "Password="
%>

The script didn't work and I received the following Message:

Microsoft JScript runtime error '800a1391'

'_' is undefined

/Connections/user_logins.asp, line

Any direction you guys can provide would be greatly appreciated. (This script is for a login page)

Need to download code?
