Non-ADO?

If I am using ASP and access an Access database, but I am not using ADO,
what is the name of the database methodology I am using ?

Are we supposed to read your mind? Give us an example.

^^^^^^

What makes you think that isn't ADO?

Well, you ARE using ADO (see that "adodb.recordset" line?). What you are
doing is using the deprecated MSDASQL provider (which is loaded by default
when you don't specify a provider in your connection string) to connect to
the obsolete Access ODBC driver.

By reading this sentence, you should get an idea about why this practice is
not recommended, even if I had left out the words "deprecated" and
"obsolete": by making ADO use a provider to communicate with a separate data
access library, you are adding an extra, and unnecessary, layer of software
between your code and the database.

Simply use the native Jet OLE DB provider. The only time the MSDASQL
provider should be used is when a native provider for your database does not
exist, or does not provide the functionality you need. Neither of these is
the case with Jet.
The other thing you are doing, also highly discouraged BTW, is failing to
use an explicit connection object. By supplying a string instead of a
connection object in the rs.open statement, you are causing ADO to open an
implicit connection. This is bad because:
1. You have no direct control over the connection and thus cannot explicitly
close it without accessing the recordset's ActiveConnection property.
2. Using implicit connections can disable ADO Session Pooling, resulting in
too many connections being opened to the database.

Always create and open an explicit connection object and use it for
subsequent database activity. You are not really saving yourself any time
when you use implicit connections, and you could definitely be causing
problems for your web server.

Ok, I have replaced my connection string with ...
myDSN = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
Session("SystemDatabaseName")

I'm not quite sure what change to make to change to an explicit connection
object. Can you give me an example?

Set conn = Server.CreateObject("ADODB.Connection")
myDSN = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
Session("SystemDatabaseName")
conn.Open myDSN

dim cn
set cn=createobject("adodb.connection")
cn.open myDSN
....
rs1.open mySQL,cn,,,1

or

set rs1=cn.Execute(mySQL,,1)

I think I'm already doing that in a round-about fashion ... this is what I
have in my "settings.asp"....

myDSN = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
Session("SystemDatabaseName")
set rs1=server.createobject("adodb.recordset")
rs1.CursorLocation = 3
rs1.CursorType = 3

To do it the way you suggest would be ...

dim cn
myDSN = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
Session("SystemDatabaseName")
set rs1=createobject("adodb.connection")
rs1.open myDSN
set rs1=cn.Execute(mySQL,,1)

Is that correct?

TIA,
PW

PS,
Bob, you're a fantastic help, thanks!

Ummm. You should use "cn" instead of "rs1" in the above 2 statements. "rs1"
is already a recordset object.
set rs1=cn.Execute(mySQL,,1)
Is that correct?

Almost.
If you are going to use cn.Execute to open your recordset, then there is no
need for the "set rs1=server.createobject("adodb.recordset")" line in your
include file. Also, using Execute causes your previous settings of
CursorLocation and CursorType to be ignored. If you really want to control
the cursor type and location, do not use Execute to return a recordset.
Instead, create the recordset and set its properties as you show above, then
create and open a connection, then use the recordset's Open method to open
the recordset as I showed above.
